A 14-year-old scientist took home $25,000 from a national science competition for inventing a liquid bandage that could replace antibiotics.

Kara Fan from San Diego, CA was won the 3M Young Scientist Challenge in St. Paul, Minnesota. Fan came up with a nano particle liquid bandage that could replace the overuse of antibiotics and potentially reduce the development of superbugs.
來自加利福尼亞州圣地亞哥的Kara Fan贏得了明尼蘇達州圣保羅市的3M青年科學家挑戰賽。Fan發明了納米顆粒液體繃帶,能解決抗生素濫用問題,可能會減緩超級細菌的發展。

“I want to show my invention of the nanosilver liquid bandage to more people. I think it is important for more people to be aware of antibiotic-resistance bacteria crisis and do something about it,” Fan said.

The 3M Young Scientist Challenge is a national competition for middle school students that takes place every year. The students are tasked with coming up with an idea or invention that tackles existing issues.

Ten finalists are chosen to compete for the title of “America’s Top Young Scientist” and a grand prize of $25,000. After being selected, they work with scientists at to make their idea come to life.

Each contestant is judged on their invention’s creativity, scientific knowledge, persuasiveness and communication, and overall presentation.

Other finalists included Jaya Choudray, who invented an airflow control robot that works to reduce energy consumption in a home, and Caroline Crouchley, who invented a climate-friendly transportation system that would eliminate the need for a diesel engine or electric motors.
其他決賽選手有Jaya Choudray,發明了一個可以減少家庭能源消耗的氣流控制機器人;Caroline Crouchley發明了一種氣候友好型交通系統,可以省去對柴油機或電動機的需求。

3M holds the competition for students in grades 5-8 because research has shown that their interest in science fades after these years.
