Photothermal materials as well as their forms and structures play a crucial role in the performance and applications of solar-driven devices. There is a growing demand for low-cost, easy-to-shape, and eco-friendly photothermal materials to meet sustainable development. Therefore, a green photothermal ink with excellent photothermal capacity and highly accessible via Chinese ink and alginate is proposed. This photothermal ink can be easily fabricated and shaped into 0D to 3D (e.g., granules, fibers, films/felts, and sponges) solar-driven devices by simple processes. Among them, the photothermal sponge displays excellent evaporation performance in solar desalination with an evaporation rate of 1.44 kg m −2 h −1 under one solar irradiation. The photothermal felt can accelerate ice melting and absorb the melted ice and prevent the substrate from freezing again. The photothermal granules can capture the moisture from the humid air and release the absorbed water under sunlight. The present photothermal ink provides a good strategy for solar-driven devices in different practical applications.

ABSTRACT The key factor in photothermal therapy lies in the selection of photothermal agents. Traditional photothermal agents generally have problems such as poor photothermal stability and low photothermal conversion efficiency. Herein, we have designed and synthesized an isoindigo (IID) dye. We used isoindigo as the molecular center and introduced common triphenylamine and methoxy groups as rotors. In order to improve the photothermal stability and tumor targeting ability, we encapsulated IID into nanoparticles . As a result, the nanoparticles exhibited high photothermal stability and photothermal conversion efficiency (67%) upon 635 nm laser irradiation. Thus, the nanoparticles demonstrated a significant inhibitory effect on live tumors in photothermal therapy guided by photoacoustic imaging and provided a viable strategy to overcome the treatment challenges.

Field-controlled micromanipulation represents a pivotal technique for handling microparticles, yet conventional methods often risk physical damage to targets. Here, we discovered a completely new mechanism for true noncontact manipulation through photothermal effects, called thermal-optical tweezers. We employ a laser self-assembly photothermal waveguide (PTW) for dynamic microparticle manipulation. This waveguide demonstrates superior photothermal conversion and precision control, generating a nonisothermal temperature field. The interaction of thermal convection and thermophoresis within this field creates a microfluidic potential well, enabling noncontact and nondestructive particle manipulation. By varying the path of PTWs in lithography and manipulating laser loading modes, diverse manipulation strategies, such as Z-shaped migration, periodic oscillation, and directional transport, are achievable. Our innovative noninvasive micromanipulation technology minimizes not only physical damage to target objects but also enables precise and diverse manipulation of micro entities, opening up new avenues for the photothermal control of cells and biomolecules.

To simply and effectively enhance the conversion capability of wearable thermoelectric textiles, a two-step in situ method is adopted to fabricate dual-shell photothermoelectric textiles which is made of polypropylene fibers with a photo-thermal layer (PPy) and a thermoelectric layer (PEDOT:Tos). The PPy is tailored to achieve high temperature and photothermoelectric effects. The PPy layer can significantly increase the photothermal conversion efficiencies of as-prepared fabric. The optimized photothermoelectric fabric can improve the generated voltage output from 294.13 to 536.47 μV under the infrared light, and its power density is up to 13.76 nW·m–2. A flexible photothermoelectric strip composed of as-prepared fabric coated with Ag particles and textile substrates with low thermal conductivity shows a voltage output of 2.25, 0.677, and 0.183 mV and a power output of 0.7031, 0.0636, and 0.0049 nW under IR light, sunlight, and on the arm, respectively. The photothermoelectric fabrics display potential as to a new smart wearable device for converting light and electricity.

Comprehensive Summary Carbon nanodots (CDs) with high photothermal performance are ideal candidates for tumor photothermal therapy (PTT). Herein, we investigated the photothermal performance of CDs synthesized from urea and citric acid via solvothermal method in dimethyl sulfoxide (DMSO) at different temperatures. Photothermal conversion efficiency (PCE) of up to 61.3% was obtained in the CDs synthesized at 150 °C (150-CDs), which is much better than the CDs synthesized at 180 °C (180-CDs). By analyzing the morphologies, chemical structures, and absorption spectra of these CDs, we found that the photothermal effect of the CDs was due to the lattice vibration of their carbonized cores, in which moderate carbonization with high content of surface carbonyl group (C=O) contributed for enhanced absorption band in deep red region with improved photothermal performance. Moreover, we also demonstrated that 150-CDs with moderate carbonized cores exhibit much better tumor PTT performance in vivo than 180-CDs with higher carbonized cores.

Organic small molecules with near-infrared (NIR) absorption hold great promise as the phototheranostic agents for clinical translation by virtue of their inherent merits such as well-defined chemical structure, high purity and good reproducibility. Probes that happen to be based on cyanine dyes exhibit strong NIR-absorbing and efficient photothermal conversion, representing a new class of photothermal agents (PAs) for photothermal therapy (PTT), and taking into account the heat susceptibility of Mitochondria (Mito), we designed and prepared a mitochondria-targeted organic small molecule (Mito-BWQ) based on thiazole orange maternal unit that can effectively kill tumor cells through the hyperpyrexia generated in the lesions under exogenous laser irradiation. The Confocal laser scanning microscope was employed to determine the preferential targeting of Mito-BWQ to the mitochondria of MCF-7 cells and U87 cells. When subjected to 600 nm laser radiation, Mito-BWQ produced an increase in temperature in test systems and this increase was dependent on both the laser power and probe concentration. In vitro tests, cytotoxicity was observed when cells were incubated with Mito-BWQ and exposed to laser irradiation. The PTT in vivo also showed that Mito-BWQ performed remarkably in tumor inhibition. This study thus provides a vital starting point for the creation of thiazole orange-based PTT formulations and promotes further advances in the field of PAs-based anticancer research and therapy.

Owing to the unique advantages of high specificity and minimal invasiveness, photothermal therapy (PTT) has been evidenced with great potential in cancer treatment. However, most photothermal agents present a shortage of photobleaching and nonspecific biodistribution in clinical application. In this study, we conjugated a new Indocyanine Green Dye (IR820) with self-assembled polypeptide (ELP) via chemical bonding in an aqueous environment. This preparation method could effectively avoid damaging the polypeptide. ELP-IR820 was fabricated as nanoconjugates with diameters of approximately 50 nm. The use of ELP-IR820 notably enhanced photothermal-mediated cytotoxicity on CT-26 cancer cells. We demonstrate that the ELP-IR820 nanoparticles significantly improved drug accumulation in the tumor and photothermal effect in vivo compared to the free dye and monomer ELP-IR820. ELP-IR820 nanoparticle also exhibited outstanding ability to cause prominent tumor tissue growth inhibition via the photothermal effect. No noticeable toxicity was detected for all treatment groups. These investigations broaden the application of NIR dyes as a multimodal photothermal therapy platform.

A SiO 2 @Au@Polyaniline (SiO 2 @Au@PAN) system has been successfully fabricated leveraging the synergistic effects of gold nanoparticles (AuNPs) to realize enhanced photothermal performance. The SiO 2 @Au@PAN exhibited strong near-infrared (NIR) absorbance, excellent photothermal conversion efficiency, good dispersibility, and outstanding photostability. The SiO 2 nanospheres as the template provided numerous binding sites for coating of AuNPs. Subsequently, aniline was grafted onto SiO 2 to form PAN, which further facilitated the growth of AuNPs. The high efficiency of electron transfer from PAN to AuNPs was utilized to enhance the photothermal performance, resulting in a photothermal conversion efficiency of 41.47%. Additionally, the effects of SiO 2 with different sizes on the anchoring of AuNPs and the impact of aniline with varying concentrations on the morphology and photothermal properties of the materials were investigated. Finally, we verified the photothermal therapeutic (PTT) effect of SiO 2 @Au@PAN at cellular level, with results demonstrating effective destruction of cancer cells. This work may provide an approach for establishing a multi-component PTT platform based on the synergistic effects of AuNPs, holding significant potential for biomedical and biochemistry applications.

Solar-driven photothermal conversion vacuum membrane distillation (SVMD) becomes an energy-efficient water treatment thanks to the thermal localization of photothermal membranes. Membrane photothermal activity and distillation performance are essential for creating photothermal composite membranes. Herein, a CuO/CF-PVDF photothermal composite membrane has been designed with flower-like copper oxide (CuO/CF) photothermal active-layer and polyvinylidene fluoride (PVDF) microporous hydrophobic separation layer. Firstly, the flower-like CuO/CF layer with the light trapping was obtained by in-situ surface oxidation on the copper foam (CF) surface. Then, by the NIPS method, PVDF microporous hydrophobic layer was scraped on one side of the CuO/CF photothermal active-layer and firmly fixed on the porous surface of CuO/CF layer by anchoring effect. The light trap consisted of CuO micron flowers and Cu(OH) 2 nanowires. The gaps among the petals increased the light refractive rate and absorption area, thus enhancing the photothermal performance of the CuO/CF. Under 1 kW‧m −2 solar irradiation, the absorption rate reached up to 95 %, and the photothermal conversion efficiency achieved 94 %. For the SVMD process, compared to current research, the CuO/CF-PVDF achieved the permeate flux of 3.34 kg‧m −2 ‧h −1 and energy efficiency of 88 % under average feed temperature. Overall, the CuO/CF-PVDF membrane has promising potential for desalination by fully using sustainable energy.

Achieving materials with low solar reflectance and minimal thermal losses is crucial for efficient solar energy harvesting, but simultaneously attaining these properties is challenging. To address this, we introduce a novel approach by engineering EGaIn photothermal nanoparticles, featuring an EGaIn core as the photothermal layer, encapsulated within a precisely designed conjugated organic shell. The conjugated organic layer was synthesized through a combination of aminoundecanoic acid and tannic acid, utilizing Schiff base and Michael addition reactions. This combination effectively regulates the thickness of the oxide layer on the EGaIn surface, thereby preserving photothermal efficiency and enhancing the interaction between EGaIn and the polymer matrix. Our method involves a hole-making process that firmly adheres nanoparticles to porous material surfaces, creating a photothermal cavity structure. This design integrates photothermal material with an insulating architecture, enhancing solar energy absorption and reducing heat loss. In practical applications, the prepared porous membrane achieved a temperature increase of 15 °C above ambient conditions, generating an output voltage of 100 mV and an output current of 38.8 mA in photothermal power generation. By overcoming traditional limitations of solar energy materials, this research establishes a way for the design and application of materials that successfully balance high solar absorption with minimal thermal losses. The developed membrane could play a pivotal role in the next generation of sustainable and efficient solar energy harvesting technologies, paving the way for more reliable and scalable renewable energy solutions.

Molybdenum oxide, as one of the important transition metal semiconductor materials with photothermal property, has received increasing attention in the field of catalysis, sensing, energy storage, and clinical biomedicine. To improve its certain limitations such as poor biocompatibility and easy agglomeration during application as biomaterials and promote its performance as photothermal agent in biomedical fields, polyethylene glycol (PEG)–modified molybdenum oxide was synthesized and the synthesis conditions during the hydrothermal process, including the pH values and the amount of PEG added, were adjusted. Owing to the reduction function of PEG, as-obtained PEG-MoO x showed good photostability and colloidal stability, which were beneficial to its application in long-term clinical photothermal therapy. In addition, cell experiments indicated that PEG-MoO x particles exhibited low cytotoxicity and ability of photothermal killing for HeLa cells. With the increase PEG-MoO x particles in solution, the photothermal ablation ability of PEG-MoO x particles for the HeLa cells was enhanced under an 808-nm NIR laser irradiation. Hence, PEG-MoO x particles have great potential in the photothermal treatment of diseases.

Photothermal conversion efficiency (PCE) plays a crucial role in tumor photothermal therapy (PTT). In this work, we developed a MoS 2 -based antitumor agent with enhanced photothermal conversion efficiency by size/morphology tailoring and IR820 loading for combinational photothermal/photodynamic therapy (PTT/PDT) of breast cancer. Among three MoS 2 -based nanomaterials, namely MoS 2 nanospheres (NSs), MoS 2 nanoflowers (NFs) and MoS 2 quantum dots (QDs), MoS 2 NSs possessed the highest PCE at 37.48%. In order to further improve the PCE, polyethyleneimine (PEI)-assisted photosensitizer IR820 decoration was carried out to prepare the MoS 2 @PEI@IR820 (MPI) nanocomposite. The introduced IR820 not only improves PCE of the MoS 2 nanomaterials to 47.08% by increasing the light absorption for enhancing PTT, but produces cytotoxic ROS for PDT, resulting in a combinational PTT/PDT with the multifunctional MPI. In addition, in vivo fluorescence (FL) bioimaging and infrared thermographic imaging have been achieved by the designed MPI nanoplatform, which has proven to be good biocompatibility, low toxicity and high PCE. This study provides a novel way for the design and construction of prominent theragnostic nanoagents for combinational PTT/PDT.
