    Abstract Image 

      This work describes a bioassisted approach for the preparation of   metal nanoparticles using yeast species Hansenula   anomala. Gold nanoparticles were prepared using gold salt as   the precursor, amine-terminated polyamidoamine dendrimer as the   stabilizer, and the extracellular material from H.   anomala as the bioreductant. It could also be demonstrated   that, using our approach, small molecules such as cysteine can   act as stabilizers as well. This synthetic approach offers a   greener alternative route to the preparation of gold sols that   are devoid of cellular and toxic chemical components. The ability   of as-synthesized gold sol to function as biological ink for   producing patterns for the analysis of fingerprints and to act as   an antimicrobial reagent is evaluated. The generality of this   toxin-free synthetic approach to other metals was assessed using   palladium and silver.
