Nanoparticles for New Pharmaceuticals: Metabolites from Actinobacteria

The resistance of common or resurgent pathogens to standard antibiotic therapies is a significant health problem, so the need for new antimicrobial sources is imperative. It is widely known that the most promising source of new drugs remains natural products, mainly those of microbial origin. Such is the case of microbial nanoparticles (NPs) which have unusual physical, chemical, and biological properties like as powerful antibacterial activities. While NPs synthesized by chemical methods involve hazardous and expensive processes, nano-biosynthesis is a green technology by which NPs are obtained through biological processes such as the reduction of a metal salt by the action of biomolecules.
