“…More recently, other nanostructured metal sulfides with unique physical and chemical properties and promising photodynamic response for cancer treatment have been reported. Among them, iron sulfide [ 78 ], silver sulfide [ 79 , 80 ], bismuth sulfide [ 81 , 82 ], and cobalt sulfide [ 83 ] stand out. Iron sulfide comprises iron and sulfur at different proportions and exists in different phases, such as Fe 1− x S (pyrrhotite), FeS (mackinawite), FeS 2p (pyrite), Fe 3 S 4 (greigite), Fe 9 S 11 (smythite), and FeS 2m (marcasite) [ 78 ].…”

Photodynamic therapy (PDT) utilizes photosensitizers (PSs) to produce reactive oxygen species (ROSs) upon irradiation, which causes the shutdown of vessels and deprives the tumor of nutrients and oxygen, and in turn induces adverse effects on the immune system. However, significant efforts are needed to increase the efficiency in PDT in terms of light delivery to specific PSs for the clinical treatment of tumors located deep under the skin. Even though PDT offers a disease site-specific treatment modality, current efforts are directed to improve the solubility (in body fluids and injectable solvents), photostability, amphiphilicity (for tissue penetration), elimination, and systemic toxicity of traditional PSs based on porphyrin derivatives. Nanostructured materials show promising features to achieve most of such combined efforts. They can be artificially engineered to carry multiple theranostic agents onto targeted tumor sites. However, recent studies on photosensitive Cd-based nanostructures, mostly used in PDT, indicate that leeching of Cd2+ ions is stimulated when they are exposed to harsh biological conditions for continuous periods of time, thus making them acutely toxic and hindering their applications in in vivo settings. Since nanostructured materials are not completely immune to degradation, great strides have been made to seek new alternatives. In this review, we focus on the latest advances of Cd-free nanostructured metal transition sulfides (MTSs) as alternative PSs and study their high-energy transfer efficiency, rational designs, and potential applications in cancer-targeted PDT. Nanostructured MTSs are discussed in the context of their versatility to serve as phototherapy agents and superior properties, including their strong absorption in the NIR region, excellent photothermal conversion efficiency, controlled reactive oxygen species (ROS) production, versatile surface chemistry, high fluorescence, and structural and thermal stability. We discuss the latest advancements in correlating the self-aggregation of MTSs with their passive tumor cell targeting, highlighting their ability to efficiently produce ROSs, and mitigating their dark toxicity through polymeric functionalization. Treatment of deep-seated tumors by using these PSs upon preferential uptake by tumor tissues (due to the enhanced permeability and retention effect) is also reviewed. We finally summarize the main future perspectives of MTSs as next-generation PSs within the context of cancer theranostics. Graphical Abstract

“…In recent years, bismuth sulfide (Bi 2 S 3 )-based semiconducting chalcogenides are novel smart materials, which have received special attention in gas sensors, photodetectors, supercapacitors, thermoelectric, photocatalysis, and imaging applications. − The reasons are caused by their low band gap energy ( E g = ∼1.7 eV), high absorption coefficient (10 4 –10 5 cm –1 ), and being a reasonable good light absorber (∼5%) . The prior reports also revealed that high electrical transport properties of Bi 2 S 3 could be enhanced by increasing an electron carrier movement in photocatalysis , and electrochemical sensors. , The performance greatly depends on the morphology, microstructure, size, etc.…”

A nanocomposite containing palladium nanoparticles embedded on bismuth sulfide nanorods (Pd@Bi2S3) was synthesized based on a solvothermal method. The structural features, composition, and morphology were characterized by XRD, FT-IR, FE-SEM-EDS, FE-TEM, HAADF-STEM, XPS, N2 physisorption, and UV–vis. Further electrochemical measurements by EIS, CV, DPV, and LSV techniques were done. It revealed that Pd@Bi2S3/GCE were exploited as electrochemical sensors for the detection of toxic mercuric ions (Hg2+), which provides a wide linear range of 0.049–445 μM, excellent sensitivity of 1.17 μA μM–1 cm–2, and detection limit of 13.5 nM. The modified electrode has also been successfully applied for the detection of Hg2+ in sea fish, river fish, and water samples. The Pd@Bi2S3/GCE signifies a robust, usability, and highly effective method for trace level detection of Hg2+ ions. Furthermore, these Pd@Bi2S3 bifunctional catalysts were discovered to have good photoreduction activity for Hg2+ ions upon the visible-light irradiation.

“…Even films can be grown by electrochemical deposit. Within physical processes, it is possible to grow thin films by sputtering; pyrolysis spray, electron gun evaporation and vacuum evaporation, among others 7,[12][13][14][15] Vacuum evaporation is a simple, replicable and fast technique used to deposit thin films from high purity materials 16 . In this work the vacuum evaporation technique was used to deposit satisfactory thin layers of bismuth sulfide, polycrystalline, very close to the stoichiometry of the compound, and with good electro-optical properties; this technique has been little used, although it has the advantage of being highly reproducible 17 .…”

Bismuth (III) sulfide thin films are prepared on glass substrates by physical vapor deposition technique. Then, the films are annealed at different temperatures from 150 to 350°C with nitrogen and nitrogen-sulfur atmospheres, respectively. The effect of annealing temperature on the optoelectronic properties is investigated. The layers were characterized using ultraviolet-visible spectroscopy, XRD, Raman spectroscopy, EDS analysis and Hall effect. The film annealed at 250°C in a nitrogen-sulfur atmosphere exhibited the best condition with an initial thickness of 106 nm and band gap of 1.37 eV. Also, Bismuthinite phase was obtained, close to the stoichiometry with 59.95 and 40.05 at % for bismuth and sulfur, respectively. The charge carrier concentration of 6.9x10 19 cm -3 with a n-type conductivity, the resistivity of 0.19 Ω-cm, and mobility of 0.44 cm 2 V -1 s -1 are obtained.
