Researchers from the University of Chicago and the University of California have developed an innovative patch. According to the authors of the project, it can help fight infections caused by antibiotic-resistant bacteria. The device uses a light electrical discharge. It aims to reduce the activity of harmful genes in infectious bacteria and inhibit their growth. The patch has been named BLAST (Bioelectronic Localized Localized Antimicrobial Stimulation Therapy). In the study, the patch was attached to pig skin along with a hydrogel to create an acidic environment necessary to activate the bacteria. Applying a weak electrical signal of 1.5 volts for 10 seconds every 10 minutes for 18 hours stopped 99% of their formations. Despite the successful tests, the researchers emphasize that there is still a lot of work ahead before the device can be put into practice. A wireless device to monitor infections without the use of drugs is also being considered
