IBM Research and Institute of Bioengineering and Nanotechnology (IBM) in Singapore recently announced that they have developed an antimicrobrial hydrogel that destroys drug-resistant bacteria on contact. When the hydrogel is applied it breaks through the biofilm of a contaminated area while its positive charge attracts negatively charged microbial membranes. The scientists say the hydrogel can rupture a bacteria's membrane without harming healthy cells.
