Biogenic sulfur-based nanocrystals: methods of fabrication and applications

Abstract:

The present review work describes the achievements about the biosynthesis of metal sulfide nanoparticles, or sulfur-based NPs (S-NPs). In general, biosynthesis is performed by utilizing living organisms or derivatives like plant extracts, single biomolecules, and viruses. Among the living organisms are bacteria, fungi, and algae, by which the biosynthesis is generally performed intracellularly or extracellularly, mediated by specific enzymes, proteins, and peptides. Commonly, metal and sulfide salts are supplied to the reaction solution with cell biomass or free-cell extracts. In many cases, the biosynthesis of S-NPs occurs without adding a sulfide source, in this case, the sulfur source is synthesized by the organisms through certain pathways, the participation of peptides, enzymes, and proteins. Diverse types of sulfide NPs have been synthesized with diverse properties highly dependent on several conditions such as …
