  • Researchers here in Korea have developed a new type of antibiotic film that kills bacteria

  • and germs in a matter of minutes, saving both time and money.

  • Sohn Jung-in shows us how it works.

  • This is an antibiotic nanofilm newly developed by local researchers.

  • When they dribble a few drops that contain germs onto it, most of the bacteria die within

  • five minutes. Looking through the microscope, the germs

  • are destroyed. The sharp, rough surface of the nanofilm acts

  • like the edge of a knife,... ripping apart the cell-wall of bacteria on contact.

  • "These blades are literally nano-size, which means that it causes no harm when a person

  • touches it, but when it is brushed against bacteria, their cell-walls are torn off, which

  • eventually kills them."

  • It takes over an hour to kill germs via oxidation, but it takes just 15 minutes using this new

  • wall-destroying material. It uses a cheaper version of nanographene

  • and titanium oxide, which costs almost one-tenth the amount of commonly used silver nanoparticles.

  • Experts believe they can expand their research to come up with other types of sterilizing

  • products for sanitation in the city, including waste water treatment.

  • "Using this new type of technology, we anticipate to easily get rid of bacteria lurking at public

  • facilities such as on handles or seats in buses, subways and bathrooms."

  • The results have been featured in the renowned academic journal "Advanced Functional Materials."

  • Sohn Jung-in, Arirang News.
