Nanotechnology-based biosensor for the detection of harmful bacteria in potable water

(Nanowerk News) Water distribution systems represent potential targets for terrorist activity because of the need for water in every sector of our industrialized society. The deliberate contamination of water reservoirs or pipes with biological agents such as pathogens or biotoxins might constitute a mass destruction bioweapon.

With this in mind, the SPS Multi-Year Project NANOtechnology inspired biosensor with photo-responsive Liquid Crystals – NANO-LC, launched in August 2020, aims at investigating a novel nanotechnology-based biosensor specifically utilized for the detection of harmful bacteria intentionally or unintentionally dispersed in potable water. Nanotechnology-based biosensor for the detection of harmful bacteria in potable water The nano-inspired device makes use of a chemically functionalized gold nanoparticle (Au NPs) array (for the selection of specific pathogens) layered with a photo-responsive liquid crystal (LC) film (for real-time detection) and with a microfluidic circuit. NANO-LC is part of the NATO Science for Peace and Security (SPS) Programme and contributes to NATO’s strategic objectives by
