Nanoparticles have been found to have remarkable antibacterial action that can dramatically shorten the duration of bacterial infections and reduce the chances of resistance. Researchers at the University of California, San Diego have developed a new type of nanoparticle that targets the bacteria responsible for common infections. These nanoparticles are able to bind to the bacterial membrane and block the entry of nutrients, causing the bacteria to die. This was a more effective approach than traditional antibiotics, which can take longer to work. The nanoparticles also showed less toxicity to the surrounding human cells, making them a safer alternative to existing treatments.
