Nanogel coatings can prevent bacteria from attaching in drinking water distribution systems (DWDS).
This publication shows the effectiveness of poly(N-isopropylmethacrylamide)-based nanogel coating on DWDS pipe materials, proving that they can be deposited on typical materials in the setting, and work against bacteria that are likely found in such surroundings – Sphingomonas and Pseudomonas. With four-hour adhesion and 24-hour biofilm assays, researchers show that the nanogel coating resulted in an adhesion reduction of up to 97% and biofilm reduction of up to 98%, compared to non-coated surfaces.
