A revolutionary breakthrough in bioengineering and the fight against microbes has occurred in Singapore in the first half of February. Finally concluding research started in 2007, with the object of studying the application of polymer and peptide nanoparticles in the field of fighting bacteria, the study has produced a hydrogel that uses electrostatic interactions with the bacteria to destroy their cell walls, thus killing them. The hydrogel is biocompatible and is absorbed by the body once it has killed the bacteria. The application can be used to coat fillings and dental implants, thus fighting off antibiotic resistant bacteria in the mouth.
