A Cleaner Doctor's Kit: Tiny Bubbles Mean Huge Improvements Lance Frazer Abstract
Current methods for sterilizing medical and dental instruments can be harsh on both the instruments themselves and the environment. So two Georgia researchers are are proposing cavitation as a safer, more sustainable sterilization method. Cavitation is the application of acoustic energy to a liquid to create bubbles, which release energy as they collapse. Experiments to date combining cavitation with increased hydrostatic pressure in an antimicrobial solution have yielded a bacterial kill rate of 90% within 1 minute.
