VA 14-year-old scientist took home $25,000 from a national science competition for inventing aliquid 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 ofantibiotics and potentially reduce the development of superbugs。
来自加利福尼亚州圣地亚哥的Kara Fan赢得了明尼苏达州圣保罗市的3M青年科学家挑战赛。Fan发明了纳米颗粒液体绷带，能解决抗生素滥用问题，可能会减缓超 级细菌的发展。
"I want to show my invention of the nanosilver liquid bandage to more people. I think it isimportant for more people to be aware of antibiotic-resistance bacteria crisis and dosomething about it," Fan said.
The 3M Young Scientist Challenge is a national competition for middle school students thattakes place every year. The students are tasked with coming up with an idea or invention thattackles existing issues.
Ten finalists are chosen to compete for the title of "America's Top Young Scientist" and a grandprize of $25,000。 After being selected, they work with scientists at to make their idea come tolife。
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 toreduce energy consumption in a home, and Caroline Crouchley, who invented a climate-friendlytransportation system that would eliminate the need for a diesel engine or electric motors.
3M holds the competition for students in grades 5-8 because research has shown that theirinterest in science fades after these years.
