IBM researchers created a new type of nanoparticles that are capable of destroying the membrane walls of certain drug-resistant bacteria strains, leaving the cells to harmlessly thaw without any trace. The new system works by using biodegradable plastic to engineer electrically charged nanoparticles that in turn attract to the bacteria’s opposite charge, in turn destroying the membrane walls hence the cell entirely. Certain types of traditional antibiotic medicines work by blocking certain types of microorganisms that can cause infections from multiplying by interfering with their internal contents, including DNA, or external parts like the membrane wall. Mostly, these medicines work very well in destroying all (which is why it is critical to follow dosage instructions from your physician, and continue to take your prescribed medication even after you feel better) bacteria over the course of treatment, but there are times when not every bacterial cell is killed which could later become drug resistant.
