Facile ultrathin film of silver nanoparticles for bacteria sensing.

Parul Taneja, V Manjuladevi, R K Gupta, Sandeep Kumar, K K Gupta,

Silver nanoparticles (AgNPs) exhibit excellent anti-microbial and bactericidal properties. Due to bacterial abhorrence for AgNPs, it is difficult to develop a label-free, sensitive and low-cost bacteria sensor using them. In the present article, we report that an ultrathin and uniform Langmuir-Schaefer (LS) film of AgNPs can be employed for bacteria ... Read more >>
