In this work, a novel BiOCl/Cu-doped Bi 2 S 3 photocatalyst was designed to efficiently remove ciprofloxacin (CIP) with high photocatalytical activity and good stability over a wide pH range. Compared with Cu-doped Bi 2 S 3 , Bi 2 S 3 , BiOCl, BiOCl/Bi 2 S 3 , and Cu-doped BiOCl, the photocatalytical degradation rate of CIP (97.1% at 20 mg/L) over BiOCl/Cu-doped Bi 2 S 3 was enhanced by about 84.77, 44.23, 2.95, 2.27, and 1.96 times within 20 min, respectively. Notably, the BiOCl/Cu-doped Bi 2 S 3 photocatalyst also displayed high photocatalytical performance in the degradation of other antibiotics including norfloxacin, ofloxacin, and tetracycline (40 mL, 20 mg/L; 88.3%, 100%, and 95.2% of degradation rate within 30 min, respectively) under visible light irradiation. Radical trapping experiments and electron spin resonance technique indicated that superoxide radicals (•O 2 − ) and photogenerated holes (h + ) played crucial roles in the photocatalytic degradation of CIP. Finally, the possible CIP degradation pathways was proposed by detecting the CIP intermediates in photocatalytical reaction process.

A novel fibrous BiVO 4 /Bi 2 S 3 /MoS 2 heterojunction is facilely constructed by simple electrospinning and hydrothermal processes. Bi 2 S 3 was formed concurrently along with the hydrothermal synthesis of MoS 2 on to the porous structure of BiVO 4 fibers. The BiVO 4 /Bi 2 S 3 /MoS 2 (BBM) heterojunction is organized with MoS 2 nanosheets of several layers in thickness encapsulating both on the Bi 2 S 3 nanorod around 40 nm in diameter and fibrous BiVO 4 template. The BiVO 4 /Bi 2 S 3 /MoS 2 heterojunction shows significant enhancement of visible light absorption in the region of 500–800 nm and photocurrent of 3 times higher than that of pure BiVO 4 . By adjusting the precursor concentration of MoS 2 , the optimized BBM-2 sample presents 4.9 and 9.5 times higher of the photodegradation efficiency and apparent reaction rate constant respectively, than that of pure BiVO 4 fibers after 120 min under visible light irradiation . The present work will provide a new strategy to the design of Bi-contained nanofibrous heterojunctions with high photocatalytic activity for the applications in energy storage and conversion.

The optical and electronic properties of plasmonic semiconductor nanomaterials have attracted a lot of attention. In this study, sulfur vacancies was regulated to achieve carriers density of 10 17 ~ 10 23 cm −3 , with the characteristics of localized surface plasmon resonance (LSPR). Since the excitation of LSPR, the plasma electrons on the semiconductor surface are elevated to a higher energy state. These electrons can overcome the energy barrier between BS and Cd 0.5 Zn 0.5 S (CZS), directly transferred to the conduction band (CB) CZS components as electron donor. This effect may cause more electrons on the semiconductor CB to react with H 2 O to generate more hydrogen. By calculating the Debye length, the scale of the charge effect in the plasma is measured. It can be proved that LSPR is instrumental in the available separation of electrons and holes in semiconductors, and significantly improves the hydrogen production effect of CZS/BS-1.5 nanocomposites. This research furnishes new insights for the construction of efficient and novel polyphase photocatalysts.

One of the main diseases contributing to human death are malignant tumors. Phototherapy is a promising approach for cancer therapy, and functional nanoparticles with targeting ligands are commonly used to improve the therapeutic efficiency. However, recent studies have shown that nanoparticles in contact with a biological fluid can rapidly form a “protein corona” on their surface, which will remarkably decrease the targeting ability. Here, we describe the preparation of hybrid nanomaterials with Bi 2 S 3 nanorods as the core, and fluorescein-isothiocyanate and folic acid-modified human serum albumin (HSA-FITC-FA) as the shell. By using fluorescent binding label (FITC) and imaging techniques, we discovered the image of the cell lysosomes, indicating that the photothermal therapy agent was predominantly targeted to and accumulated in lysosomes. Combined with photothermal therapy agent (Bi 2 S 3 nanorods) and targeting ligand (FA), the obtained product shows enhanced photothermal therapy under near-infrared region laser irradiation. Additionally, SDS-PAGE shows that the modified HSA shell could remarkably reduce the reabsorption of protein corona from blood serum, minimized the adverse effect of protein corona on targetability. Taken together, the results indicate that our strategy has the potential for preparing efficient photothermal nanomaterials with image-guided subcellular organelle-targeting cancer cell ablation ability.

A heterojunction structure of BiVO 4 coupled with a narrow bandgap photocatalyst Bi 2 S 3 was fabricated forming a composite material with strong capacity in visible light absorption and enhancement in the separation rate of photogenerated charge carriers owing to their suitable band structures. As a result, efficiency of hydrogen production through photoelectrocatalysis is highly enhanced. The morphology and composition of as-prepared sample electrodes are measured through X-Ray Diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS). The performance of the hybrid nanostructure Bi 2 S 3 /BiVO 4 photoelectrode was found to be related to the growing process of Bi 2 S 3 nanowire during the hydrothermal preparation process. The composited Bi 2 S 3 /BiVO 4 photoanode achieved a photoconversion efficiency of 2.9% which is nearly 3-fold that of the bare BiVO 4 electrode under visible light irradiation, while the hydrogen production was greatly enhanced by nearly 5-fold in the photoelectrocatalytic hydrogen production reaction.

We developed a facile in-situ growth method to construct amorphous-based Bi 2 S 3 /Bi 2 WO 6 heterostructures at room temperature. As demonstrated by HRTEM , XPS and EDX-mapping, amorphous state Bi 2 S 3 dispersed uniformly on the surface of crystalline Bi 2 WO 6 hollow spheres. The photocatalytic activities of prepared Bi 2 S 3 /Bi 2 WO 6 heterostructures were evaluated by the photodegradation of RhB and TC under visible light irradiation, indicating that the introduction of appropriate amorphous Bi 2 S 3 significantly improved the photocatalytic activity of Bi 2 WO 6 . The amorphous/crystalline contact in Bi 2 S 3 /Bi 2 WO 6 heterostructures played a crucial role in the enhancement of photocatalytic efficiency. Based on DRS, photoluminescence spectra, photocurrent intensity, electrochemical impedance spectroscopy and OCVD measurements, it was proposed that the enhanced performance could be ascribed to increased visible light utilization, promoted separation efficiency and prolonged life time of photogenerated electron-hole pairs by the introduction of amorphous Bi 2 S 3 . This work may provide new insights into the construction of amorphous-based composited heterostructures for improving photocatalytic activity.

One-dimensional (1D) belt-like Bi 2 S 3 /BiOCl composites were synthesized by a facile one-pot solvothermal method, using bismuth subsalicylate as the Bi source and, in particular, as the morphological template. The synthesized composites were characterized by many techniques, such as XRD, SEM, XPS, TEM and UV–vis diffuse reflectance and photoluminescence spectra. Photocatalytic activity of the composites was evaluated via catalytic degradation of salicylic acid (SA) and Rhodamine B (RhB) under visible light irradiation. The belt-like composites show a heterojunction structure in which the Bi 2 S 3 nanoparticles are uniformly dispersed in the BiOCl matrix with dominant exposed (010) facets. They exhibit enhanced photodegradation efficiency in comparison with pure belt-like Bi 2 S 3 and BiOCl. With increasing Bi 2 S 3 content, the photodegradation efficiency of the composites increases then decreases. The Bi 2 S 3 /BiOCl composite with a Bi 2 S 3 content of ∼2% exhibits the highest photocatalytic activity. The apparent first-order photodegradation rate constants of the composite for SA (∼0.048 h −1 ) and RhB (∼0.299 min −1 ) are significantly higher than those of the pure BiOCl and Bi 2 S 3 for SA (∼0 and ∼0.0007 h −1 ) and RhB (∼0.102 and ∼0.002 min −1 ), respectively. The enhancement in photocatalytic activity is attributed to the efficient separation of photoinduced electrons and holes along with the increased specific surface area and visible-light absorption. The holes and superoxide radicals are the major active species. In addition, the belt-like Bi 2 S 3 /BiOCl photocatalysts exhibit excellent stability and reusability. This work provides a facile strategy for synthesis of 1D hierarchical Bi-based composite photocatalysts, and demonstrates the potential of belt-like Bi 2 S 3 /BiOCl composites for application in environmental remediation.

In this paper, Bi 2 S 3 nanospheres with size of 212 nm were prepared by a simple hydrothermal process. The selectively enhanced antibacterial effects of Bi 2 S 3 nanospheres with three classes of ineffective antibiotics, β-lactam (cefuroxime, CXM; cefotaxime , CTX and piperacillin , PIP), quinolone (ciprofloxacin, CIP) and aminoglycoside (gentamicin, GEN) against clinical isolated methicillin-resistant Staphylococcus aureus (MRSA) were investigated for the first time. GEN shows significantly synergistic growth inhibition against MRSA when combined with Bi 2 S 3 nanospheres, while CXM, CTX, PIP and CIP do not. Raman spectroscopy and Z potential studies reveal that Bi 2 S 3 could interact with GEN and the combination showed small electronegativity , which probably induced the increase of GEN content in cytoplasm of bacteria. Furthermore, the combination of Bi 2 S 3 nanospheres and GEN can destroy the bacterial membrane function and induce more bactericidal reactive oxygen generation than that of Bi 2 S 3 or GEN alone. The cytotoxicity test indicates that the combination of Bi 2 S 3 and GEN presented low toxicity to human normal hepatocyte L02. This work shows that Bi 2 S 3 nanospheres can be used to enhance the action of ineffective antibiotic GEN against MRSA, thus strengthening the antibiotic capacity for fighting MRSA infections.

Along with continuous growing widespread adulterations of botanical drugs, the necessity for drug quality monitoring has become more popular than ever. Considering that antioxidants are widely found in natural plant pharmaceuticals, gallic acid (GA) is often regarded as the reference standard to make sure whether these are up to grade as guided by Chinese Pharmacopeia. Herein, a novel Bi 2 MoO 6 /Bi 2 S 3 photoelectrochemical sensor has been successfully involved toward selective GA analysis to supervise drug quality, in which γ-Bi 2 MoO 6 nanobelts were treated as template nanocrystal and scaffold. Such Bi 2 S 3 accommodated in Bi 2 MoO 6 nanobelts render platform with excellent light-harvesting capability, selectivity and reproducibility. Concerned mechanism was in-depth pursued through theoretical computation and morphology speculation, inferring that two aspects mainly contribute to the findings: (1) engineering particular structure brings about surface dangling bonds , which raises the likelihood of electrostatic interaction with opposite charges; (2) appending Bi 2 S 3 to the Bi 2 MoO 6 nanobelts acted as a new avenue to mediate photoelectrochemical behavior, nearly devoid of interference effect. Our work opens up broad possibilities for finely distinguishing different antioxidants. As the extension of this simple and valid strategy, photoelectrochemistry will become a potent backing for quality guaranty in drug field, which offers an entry into ensuring good consistency in batch production .

Herein, a robust photoelectrochemical (PEC) immunosensor was constructed based on an n-n heterojunction between a copper-porphyrin-based metal organic framework and Bi 2 S 3 (Bi 2 S 3 @Cu-TPyP) for efficient detection of gentamicin (GEN). The integration of Cu-TPyP features (enhanced electron transfer capability, improved photoabsorption performance, large specific surface area, and high antibody bioaffinity) with Bi 2 S 3 characteristics (narrow bandgap and visible light absorption capacity) established an efficient interfacial architecture. Enhanced separation of photogenerated electron-hole pairs and improved photoelectric conversion efficiency in the Bi 2 S 3 @Cu-TPyP heterojunction contributed to the amplified photocurrent. The immunosensor exhibited an ultralow detection limit of 0.041 fg mL −1 (1.0 fg mL −1 –1.0 ng mL −1 linear range) with high selectivity and validated applicability in analyzing GEN across diverse food matrices. This study establishes a PEC biosensing paradigm enabling ultrasensitive and rapid antibiotic monitoring in food products due to the synergistic signal amplification mechanisms without compromising specificity.

Colorectal cancer ranks as the third most prevalent cancer globally, with its incidence increasing in many developed countries. While chemotherapy demonstrates efficacy for certain patients, it is associated with significant side effects, and prolonged treatment may result in drug resistance. Consequently, this study synthesized Bi 2 S 3 nanosheets via the solution-based method and integrated them with mesoporous silica exhibiting excellent pore channel properties to develop the Bi 2 S 3 @mSiO 2 -PEG/5-FU nanomaterials. Photothermal testing revealed that Bi 2 S 3 @mSiO 2 -PEG/5-FU exhibited superior photothermal heating performance, remarkable photothermal stability, and a photothermal conversion efficiency of 28.3%, enabling effective photothermal therapy. The drug loading capacity of Bi 2 S 3 @mSiO 2 -PEG/5-FU was determined to be 24.8%, with enhanced drug release under acidic conditions and laser irradiation, thereby improving chemotherapeutic efficacy and achieving synergistic effects between chemotherapy and photothermal therapy. Furthermore, Bi 2 S 3 @mSiO 2 -PEG demonstrated robust CT imaging capabilities (14.95 HU mg/mL), establishing the Bi 2 S 3 @mSiO 2 -PEG/5-FU nanomaterials as a platform with integrated diagnostic and therapeutic functionalities.

Periodontitis is a prevalent chronic inflammatory disease driven by bacterial infection, whose treatment remains challenging due to persistent inflammation and limited tissue regeneration. Here, we developed an injectable and thermosensitive hydrogel (Bi 2 S 3 @Gel) composed of hyaluronic acid/Pluronic F127 and Bi 2 S 3 nanorods (Bi 2 S 3 NDs), which synergistically combines antibacterial and anti-inflammatory functions. Under near‑infrared (NIR) irradiation, Bi 2 S 3 @Gel exhibits excellent photothermal properties. It generates mild hyperthermia while simultaneously amplifying reactive oxygen species (ROS) and depleting glutathione (GSH), leading to effective bacterial eradication. Simultaneously, the hyaluronic acid matrix prolongs local retention, suppresses M1 macrophage polarization, and promotes tissue repair. In vitro studies confirm favorable biocompatibility, potent antibacterial activity, and effective immunomodulation. In vivo, Bi 2 S 3 @Gel accelerates diabetic wound healing and promotes periodontal regeneration comparable to minocycline treatment, as evidenced by reduced inflammation, enhanced collagen deposition, and significant alveolar bone restoration. Collectively, Bi 2 S 3 @Gel integrates antibacterial, anti‑inflammatory, and regenerative capabilities, offering a promising therapeutic platform for periodontitis and other chronic infectious diseases.
