Abstract

Described herein is method for manufacturing a nanoparticle mixture comprising surface-capped nanoparticles for adhesion to bacteria, the method comprising the steps of providing a nanoparticle starting mixture comprising nanoparticles in a liquid, optionally mixing the nanoparticle starting mixture with a non-ionic surfactant to obtain a nanoparticle intermediate mixture, adding a capping molecule to the nanoparticle starting mixture or the nanoparticle intermediate mixture to obtain a nanoparticle mixture, optionally adjusting the pH value of the nanoparticle mixture and optionally removing the non-ionic surfactant. Also described are surface-capped nanoparticles for adhesion to bacteria obtainable by said method and a method for detecting bacteria applying surface-capped nanoparticles. Further described is the use of surface-capped nanoparticles for detecting bacterial contamination in food and/or feed or for monitoring microbiological safety of production lines for food and/or feed.
