导读:来自科罗拉多州的11岁Gitanjali Rao发明感应器赢得了大奖,被誉为“美国年轻科学家”。

A schoolgirl aged 11 has been honoured as "America’s top young scientist" for inventing a quick, low-cost test to detect lead-contaminated water.

Gitanjali Rao was selected from 10 finalists who had spent three months collaborating with scientists to develop their ideas.

Her device uses carbon nanotubes to detect the presence of lead.

Thousands of US water systems are reportedly contaminated by lead.

Gitanjali’s invention was inspired by the scandal in Flint, Michigan, where officials are facing charges, she told Business Insider.

Until now, testing reliably for lead was expensive and meant sending away samples for analysis.

But Gitanjali’s portable invention allows a sensor linked to a mobile app to give an accurate, almost immediate analysis.

Gitanjali said she wanted to further refine the device so it could eventually go on the market.

Gitanjali won a $25,000 prize for scooping the top award.
