Self-Assembly Of Nanoparticles On Live Bacterium: An Avenue To Fabricate Electronic Devices, Vikas Berry, Ravi F. Saraf

Papers in Nanotechnology

Recently, hybrid structures of microorganisms with inorganic nanoscale moieties have received great interest due to their potential in fabricating electronic systems. Electronic properties of metal nanoparticles, due to single electron transport of current[1], make them ideal material for nanodevices. Concomitantly, the nanostructure of microorganisms such as bacteria[2], viruses[3;4] and yeast[5] are attractive scaffolds for nanoparticle templating due to surface charge and biological affinities for specific molecules [2-7]. However, the key challenges in building hybrid devices are patterning nanostructures without destroying the biological construct of the microorganism and achieving active integration of biological response to the electrical transport in nanoparticle device. …
