Keywords: plasmonic biosensors, silver nanoparticles, core-shell


Silica-coated silver nanoparticles were synthesized by flame spray pyrolysis. The toxicity of the product nanoparticles was investigated against the E. coli bacteria. The feasibility of the nanosilver particles as plasmonic biosensors was examined with the physisorption of the bovine serum albumin protein.
