We have prepared novel poly(d,l-lactide-co-glycolide) (PLGA) lipid nanoparticles (PNPs) that covalently conjugate folic acid (FA) and indocyanine green (ICG), in addition to encapsulating resveratrol (RSV) (FA-RSV/ICG-PLGA-lipid NPs, abbreviated as FA-RIPNPs); these nanoparticles have been developed for simultaneous targeted delivery of anticancer drug and fluorescence imaging. The FA-RIPNPs, with an average particle size of 92.8±2.1 nm, were prepared by a facile self-assembly-and-nanoprecipitation method, and they showed excellent stability and biocompatibility characteristics. The FA-RIPNPs exhibited an RSV encapsulation efficiency of approximately 65.6%±4.7% and a maximum release ratio of 78.2%±4.1% at pH 5.0 and 37°C. Confocal fluorescence images showed that FA-RIPNPs may facilitate a high cellular uptake via FA receptor-mediated endocytosis. Furthermore, FA-RIPNPs (containing 50 μg/mL RSV) induced a 81.4%±2.1% U87 cell inhibition rate via apoptosis, a value that proved to be higher than what has been shown for free RSV (53.1%±1.1%, equivalent RSV concentration). With a formulated polyethylene glycol (PEG) shell around the PLGA core, FA-RIPNPs prolonged the blood circulation of both free RSV and ICG, which approximately increased 6.96- and 39.4-fold (t1/2), respectively. Regarding FA-RIPNP use as a near-infrared probe, in vivo fluorescence images indicated a highly efficient accumulation of FA-RIPNPs in the tumor tissue, which proved to be approximately 2.8- and 12.6-fold higher than the RIPNPs and free ICG, respectively. Intravenous injection of FA-RIPNPs into U87 tumor-bearing mice demonstrated the best tumor inhibition effect for all tested drugs, including free RSV and RIPNPs, with no relapse, showing high biocompatibility and with no significant systemic in vivo toxicity over the course of the treatment (1 month). The results obtained demonstrate the versatility of the NPs, featuring stable fluorescence and tumor-targeting characteristics, with promising future applications in cancer therapy.

Liver cancer is a leading cause of cancer morbidity and mortality worldwide, especially in China. Sorafenib (SRF) is currently the most commonly used systemic agent against advanced hepatocellular carcinoma (HCC), which is the most common type of liver cancer. However, HCC patients have only limited benefit and suffer a serious side effect from SRF. Therefore, new approaches are urgently needed to improve the therapeutic effectiveness of SRF and reduce its side effect. In our current study, we developed a self-imaging and self-delivered nanodrug with SRF and indocyanine (ICG) to improve the therapeutic effect of sorafenib against HCC. With the π–π stacking effect between SRF and ICG, a one-step nanoprecipitation method was designed to obtain the SRF/ICG nanoparticles (SINP) via self-assembly. Pluronic F127 was used to shield the SINP to further improve the stability in an aqueous environment. The stability, photothermal effect, cell uptake, ROS production, cytotoxicity, tumor imaging, and tumor-targeting and tumor-killing efficacy of the SINP were evaluated in vitro and in vivo by using an HCC cell line Huh7 and its xenograft tumor model. We found that our designed SINP showed monodisperse stability and efficient photothermal effect both in vitro and in vivo. SINP could rapidly enter Huh7 cells and achieve potent cytotoxicity under near-infrared (NIR) laser irradiation partly by producing a great amount of reactive oxygen species (ROS). SINP had significantly improved stability and blood half-life, and could specifically target tumor via the enhanced permeability and retention (EPR) effect in vivo. In addition, SINP showed improved cytotoxicity in both subcutaneous and orthotopic HCC implantation models in vivo. Overall, this rationally designed sorafenib delivery system with a very high loading capacity (33%) has considerably improved antitumor efficiency in vitro and could completely eliminate subcutaneous tumors without any regrowth in vivo. In conclusion, our self-imaging and self-delivered nanodrug could improve the efficacy of SRF and might be a potential therapy for HCC patients.

The therapy of tumor recurrence resulting from surgical resection of osteosarcoma is still a significant challenge for clinicians. In this study, we designed curcumin (CM) and indocyanine green (ICG) co-loaded poly(L-lactic acid) (PLLA) (PLLA-CM-ICG) composite microparticles , combining photothermal therapy with chemotherapy to enhance osteosarcoma therapy synergistically. PLLA-CM-ICG microparticles of sizes of (838.3 ± 5.4) nm were prepared by solution-enhanced dispersion by a supercritical CO 2 process. ICG in the PLLA-CM-ICG microparticles was more stable than free ICG. The PLLA-CM-ICG microparticles displayed pH- and near-infrared (NIR)-responsive CM release behavior. Moreover, NIR irradiation improved the anticancer activity of the PLLA-CM-ICG microparticles at a concentration of 250 μg/mL on MG-63 cells. Therefore, PLLA-CM-ICG microparticles could be employed as promising drug delivery systems for synergic photothermo-chemotherapy in osteosarcoma treatment.

Developing effective therapy to inhibit postoperative recurrence and metastasis of colorectal cancer (CRC) is challenging and significant to reduce mortality and morbidity. Here, a granular hydrogel, assembled from gelatin microgels by dialdehyde starch and interpenetrated with in situ polymerized poly(sulfobetaine methacrylate- co -N-isopropylacrylamide) (P(SBMA- co -NIPAM)), is prepared to load and lock Food and Drug Administration (FDA)-approved indocyanine green (ICG) with definite photothermal function and biosafety for photothermal therapy (PTT) combining with checkpoint inhibitor. The presence of P(SBMA- co -NIPAM) endows granular hydrogel with high retention to water-soluble ICG, preventing easy diffusion and rapid scavenging of ICG. The ICG-locking granular hydrogel can be spread and adhered onto the surgery site at wet state in vivo, exerting a persistent and stable PTT effect. Combined with αPD-L1 treatment, ICG-locking granular hydrogel-mediated PTT can eradicate postsurgery residual and metastatic tumors, and prevent long-term tumor recurrence. Further mechanistic studies indicate that combination treatment effectively promotes dendritic cells maturation in lymph nodes, enhances the number and infiltration of CD8 + T and CD4 + T cells in tumor tissue, and improves memory T cell number in spleen, thus activating the antitumor immune response. Overall, ICG-locking gel-mediated PTT is expected to exhibit broad clinical applications in postoperative treatment of cancers, like CRC.

Development of chemo/photothermal/photodynamic therapy with nanoplatforms offers a promising strategy for effective cancer treatment. Recently, all-trans retinoic acid (ATRA), as a potential antitumor drug, has attracted great attention due to its antitumor activity. In this study, a novel coumarin-containing ATRA (AC) and indocyanine green (ICG) dye-loaded nanoparticles with the targeted ligand cyclic (Arg-Gly-Asp-D-Phe-Lys) (cRGD) peptide were fabricated by self-assembly and used as a new theranostic nanoplatform for chemo/photothermal/photodynamic therapy. The as-formed nanoparticles (AC/ICG-TNPs) had a diameter of around 133 nm with uniform monodispersity. Additionally, AC/ICG-TNPs showed marked stability under normal physiological conditions. However, it could rapidly release drugs in a mild acidic microenvironment. Moreover, confocal microscopic observations confirmed that the uptake of AC/ICG-TNPs increased in the breast cancer cells, particularly in MDA-MB-231 cells, probably mediated by cRGD via specific recognition of the overexpressed integrin αvβ3. Moreover, free AC exhibited stronger cytotoxic effects than free ATRA in the MTT assay, and AC/ICG-TNPs were demonstrated to possess excellent antitumor efficacy when exposed to NIR irradiation through the combination therapy. Hence, the therapeutic method designed in this study is a good candidate for improved bioactivity of ATRA and site-specific combinational therapy against breast cancer.

In this study, we proposed a novel application of an established material by developing ingestible nanoparticles made from bovine serum albumin loaded with indocyanine green. These nanoparticles, referred to as ICG@BSA NPs, response to near infrared (NIR) laser exposure by generating reactive oxygen species. This process, known as photodynamic therapy (PDT), is designed to targeted kill vector-borne organisms. As a representative model of vectors, housefly larvae trended to uptake more protein-based ICG@BSA NPs than free ICG. This led neither to an obvious influence on larval development nor to a significant impact on the intestinal microbial population. In contrast, under NIR laser irradiation, ICG@BSA NPs could efficiently induce generation of ROS for killing larvae via damaging intestinal wall and inducing subsequent intestinal bacteria leakage. This protein-based ingestible nanoparticles integrate the independence of pesticides, pronounced PDT efficacy, and environmental friendliness, making this nanoplatform promising for controlling vector-borne organisms and associated diseases.

Objective Perineural invasion (PNI) is associated with local recurrence, distant metastasis, and a poor prognosis in pancreatic cancer. However, rare attempt was made to identified the PNI intraoperative. To facilitate precise R0 excision of the tumor, we planned to develop a fluorescent probe for intraoperative imaging of the PNI using GAP-43 as the target and indocyanine green (ICG) as the carrier. Methods The probe was created by binding peptide antibody and ICG. Its targeting was tested in vitro and in vivo using a co-culture model of PC12 and tumor cells to create an in vitro neural invasion model and a mouse sciatic nerve invasion model. The small animal imaging system and surgical navigation system confirmed the probe's potential clinical applicability. The sciatic nerve damage model was created to confirm the probe's targeting. Results We used the pancreatic cancer samples and the public database to confirm that GAP-43 was preferentially overexpressed in pancreatic cancer, particularly in PNI. PC12 cells showed high GAP-43RA-PEG-ICG probe-specific absorption after being co-cultured with tumor cells in vitro. In the sciatic nerve invasion experiment, animals in probe group displayed a significantly stronger fluorescence signal at the PNI compared to ICG-NP and the contralateral normal nerves groups. Although only 60 % of mice appeared to have R0 resections by the naked eye, small animal imaging systems and surgical fluorescence navigation systems could remove the tumor with R0 precision. The injury model used in the probe imaging experimental trials demonstrated that the probe was specifically targeted to the injured nerve, regardless of whether the injury was infiltrated by a tumor or physical. Conclusion We developed the GAP-43Ra-ICG-PEG, an active-targeting near-infrared fluorescent (NIRF) probe, that specifically binds to GAP-43-positive neural cells in an in vitro model of PNI. The probe efficiently visualized PNI lesions in pancreatic cancer in preclinical models, opening up new possibilities for NIRF-guided pancreatic surgery, particularly for PNI patients.

It is a great challenge to combat multidrug resistant (MDR) cancer effectively. To address this issue, we developed a new near-infrared (NIR) triggered chemotherapeutic agent doxorubicin (DOX) and photosensitizer indocyanine green (ICG) co-release system by aid of NIR induced photothermal effect of gold nanocages (AuNCs) and temperature sensitive phase-change property of 1-tetradecanol at its melting point of 39 °C, which could simultaneously exerted chemo/photothermal/photodynamic treatment on MDR human breast cancer MCF-7/ADR cells. This nano-sized system was constructed by filling the interior of AuNCs with DOX, ICG and 1-tetradecanol, and modifying the surface with biotinylated poly (ethylene glycol) via Au-S bonds, termed as DOX/ICG@biotin-PEG-AuNC-PCM. The DOX and ICG co-release from DOX/ICG@biotin-PEG-AuNC-PCM was much faster in PBS at 40 °C or under 808 nm NIR irradiation at 2.5 W/cm 2 than at 37 °C (e.g. 67.27% or 80.31% vs. 5.57% of DOX, 76.08% vs. 3.83% of ICG for 20 min). The flow cytometry and confocal laser scanning microscopy (CLSM) results showed, the AuNCs were taken up by MCF-7/ADR cells via endocytosis , thus enhancing DOX uptake; the biotin on AuNCs facilitated this endocytosis; NIR irradiation caused the heating of the AuNCs, triggering the DOX and ICG co-release and enhancing the distribution of DOX in nuclei, the released ICG generated ROS to take photodynamic therapy. Due to the above unique properties, DOX/ICG@biotin-PEG-AuNC-PCM exerted excellent anti-tumor effects under NIR irradiation, its IC 50 against MCF-7/ADR cells was very low, only 0.48 µg/mL, much smaller than that of free DOX (74.51 μg/mL). Statement of Significance A new near-infrared (NIR) triggered chemotherapeutic agent doxorubicin (DOX) and photosensitizer indocyanine green (ICG) co-release system by aid of NIR induced photothermal effect of gold nanocages (AuNCs) and temperature sensitive phase-change property of 1-tetradecanol at its melting point of 39 °C, was prepared, termed as DOX/ICG@biotin-PEG-AuNC-PCM, which could simultaneously exerted chemo/photothermal/photodynamic treatment on MDR human breast cancer MCF-7/ADR cells.

The development of tumor-retained and minimally invasive mRNA and photothermal therapies for superficial malignant tumors, such as breast cancer, remains a significant challenge. In this study, we present a novel tumor-retained lipid nanoparticle-microneedle (LNP-MN) patch for localized co-delivery of mRNA and the photothermal agent indocyanine green (ICG). By optimizing LNP formulations, ICG loading methodology, mRNA-to-ICG ratio, and MN matrix composition, we achieved a balanced platform ensuring high mRNA transfection efficiency and robust ICG photothermal performance. This LNP-MN platform enabled efficient intratumoral deposition, demonstrating a 15.6-fold increase in tumor accumulation compared to intravenous administration. For the first time, SARS-CoV-2 spike mRNA was combined with ICG-mediated photothermal therapy (PTT) within a single system for superficial tumor treatment. In a 4 T1 breast cancer model, this combinatorial strategy achieved significant tumor growth inhibition (75.1 %), enhanced CD8+ T-cell infiltration, and minimized systemic toxicity, outperforming monotherapies. This study pioneers the integration of PTT and mRNA-based tumor-labeling immunotherapy in a minimally invasive MN platform, offering a promising strategy for enhanced superficial cancer therapy.

Reactive oxygen species (ROS) with strong oxidability have been considered as effective agents for antitumor therapy through oxidative damage to lipids, proteins, DNA and RNA. In this work, a multifunctional hollow cobaltosic sulfide (Co 3 S 4 )/photosensitizer indocyanine green (ICG) nanocomplex (Co 3 S 4 -ICG) has been synthesized by efficiently loading ICG into the hollow Co 3 S 4 to realize synergistic antitumor therapy via chemodynamic therapy (CDT), photodynamic therapy (PDT) and photothermal therapy (PTT) under near-infrared (808 nm) laser irradiation. Co 3 S 4 nanoparticles would be degraded in tumor acidic microenvironment into Co 2+ , which locally triggers a Fenton-like reaction to produce cytotoxic hydroxyl radicals ( OH) for CDT. Co 3 S 4 -ICG could also produce singlet oxygen ( 1 O 2 ) through a multi-step photochemical process for PDT under 808 nm laser irradiation. The slow release of ICG in the tumor region was achieved due to hollow-structured Co 3 S 4 working as nanocarriers, and which has been proved an effective approach for combined CDT/PDT. In addition, Co 3 S 4 -ICG showed high photothermal conversion efficiency (40.5%) for PTT, and excellent OH generation capability via photothermal-improved Fenton reaction, leading to the synergistically improved antitumor efficacy. In vitro and in vivo experimental results confirm that the combined PTT/PDT/photothermal-enhanced CDT therapy can effectively ablate tumors with a negligible systemic toxicity. This work provides a valuable strategy for designing and constructing of a multifunctional nanoplatform for synergistic antitumor therapy of solid tumors.

Photoacoustic (PA)/near-infrared fluorescence (NIRF) dual-modal imaging-guided phototherapy has been wide explored very recently. However, the development of high-efficiency and simplified-performed theranostic system for amplifying imaging-guided photothermal therapy/photodynamic therapy (PTT/PDT) is still a great challenge. Herein, a single-light-triggered indocyanine green (ICG)-loaded PEGylation silver nanoparticle core/polyaniline shell (Ag@PANI) nanocomposites (ICG-Ag@PANI) for PA/NIRF imaging-guided enhanced PTT/PDT synergistic effect has been successfully constructed. In this study, the synthesized Ag@PANI nanocomposites are utilized not only as the promising photothermal agent but also as potential nanovehicles for loading photosensitizer ICG via π–π stacking and hydrophobic interaction. The as-prepared ICG-Ag@PANI possesses many superior properties such as strong optical absorption in the near-infrared (NIR) region, enhanced photostability of ICG, as well as outstanding NIR laser-induced local hyperthermia and reactive oxygen species (ROS) generation. In the in vivo study, PA/NIRF dual-modal imaging confirms the accumulation and distribution of ICG-Ag@PANI in the tumor region via enhanced permeability and retention (EPR) effect. Moreover, the PTT effect of ICG-Ag@PANI rapidly raised the tumor temperature to 56.8 °C within 5 min. It is also demonstrated that the cytotoxic ROS generation ability of ICG is well maintained after being loaded onto Ag@PANI nanocomposites. Remarkably, in comparison with PTT or PDT alone, the single 808 nm NIR laser-triggered combined PTT/PDT therapy exhibits enhanced HeLa cells lethality in vitro and tumor growth inhibition in vivo.

The evolution of nano-drug delivery systems addresses the limitations of conventional cancer treatments with stimulus-responsive nanomaterial-based delivery systems presenting temporal and spatial advantages. Among various nanomaterials, boron nitride nanoparticles (BNNs) demonstrate significant potential in drug delivery and cancer treatment, providing a high drug loading capacity, multifunctionality, and low toxicity. However, the challenge lies in augmenting nanomaterial accumulation exclusively within tumors while preserving healthy tissues. To address this, we introduce a novel approach involving cancer cell membrane-functionalized BNNs (CM-BIDdT) for the codelivery of doxorubicin (Dox) and indocyanine green to treat homologous tumor. The cancer cell membrane biomimetic CM-BIDdT nanoparticles possess highly efficient homologous targeting capabilities toward tumor cells. The surface modification with acylated TAT peptides (dTAT) further enhances the nanoparticle intracellular accumulation. Consequently, CM-BIDdT nanoparticles, responsive to the acidic tumor microenvironment, hydrolyze amide bonds, activate the transmembrane penetrating function, and achieve precise targeting with substantial accumulation at the tumor site. Additionally, the photothermal effect of CM-BIDdT under laser irradiation not only kills cells through thermal ablation but also destroys the membrane on the surface of the nanoparticles, facilitating Dox release. Therefore, the fabricated CM-BIDdT nanoparticles orchestrate chemo–photothermal combination therapy and effectively inhibit tumor growth with minimal adverse effects, holding promise as a new modality for synergistic cancer treatment.
