  The paper deals with differently synthesized robust metal nanoparticles using chemical synthesis approach for detection of a new pathogenic strain E. coli in water sample. The reactions have been completed using aqueous metal salt solution and trisodium citrate as a capping agent to obtain nanoparticles. The nanoparticles and their interaction against microorganisms have been characterized using UV-Vis spectroscopy and Transmission Electron Microscopy (TEM). For different concentration of sodium borohydride, surface plasmon resonance peaks have been obtained at 390 nm to 402 nm for silver nanoparticles and 518 nm to 524 nm for gold nanoparticles. It has been observed to be shifted from 520 nm to 527 nm and 395 nm to 408 nm for gold and silver nanoparticles after the interaction with E. coli respectively. Silver and gold nanoparticles have been synthesized at 80°C exhibited strong.. View More»
