Journal ArticleDOI
Extracellular biosynthesis of silver nanoparticles using the fungus Fusarium oxysporum
Absar Ahmad,Priyabrata Mukherjee,Satyajyoti Senapati,Deendayal Mandal,M. Islam Khan,Rajiv Kumar,Murali Sastry +6 more
TL;DR: It is observed that aqueous silver ions when exposed to the fungus Fusarium oxysporum are reduced in solution, thereby leading to the formation of an extremely stable silver hydrosol, creating the possibility of developing a rational, fungal-based method for the synthesis of nanomaterials over a range of chemical compositions, which is currently not possible by other microbe-based methods.
Journal Article
Biosynthesis of metal nanoparticles using fungi and actinomycete
TL;DR: An overview of the research efforts worldwide on the use of micro-organisms in the biosynthesis of inorganic nanoparticles, with particular emphasis on the recent and exciting results obtained at the National Chemical Laboratory, Pune on the biosynthetic of noble-metal nanoparticles using fungi and actinomycete is provided.
Journal ArticleDOI
Extracellular biosynthesis of monodisperse gold nanoparticles by a novel extremophilic actinomycete, thermomonospora sp
Journal ArticleDOI
Intracellular synthesis of gold nanoparticles by a novel alkalotolerant actinomycete, Rhodococcus species
Absar Ahmad,Satyajyoti Senapati,M. Islam Khan,Rajiv Kumar,R. Ramani,V Srinivas,Murali Sastry +6 more
TL;DR: Electron microscopy analysis of thin sections of the gold actinomycete cells indicated that gold particles with good monodispersity were formed on the cell wall as well as on the cytospasmic membrane, and metal ions were not toxic to the cells and the cells continued to multiply after biosynthesis of thegold nanoparticles.
Journal ArticleDOI
Extracellular Synthesis of Gold Nanoparticles by the Fungus Fusarium oxysporum
Priyabrata Mukherjee,Satyajyoti Senapati,Deendayal Mandal,Absar Ahmad,M. Islam Khan,Rajiv Kumar,Murali Sastry +6 more
TL;DR: A green chemistry approach to nanoparticle synthesis is the exciting possibility opened up by the fungus Fusarium oxysporum, which when exposed to aqueous AuCl 4 − ions reduces the metal ions and leads to the extracellular formation of gold nanoparticles.
