Drug-sniffing chips are 'huge deal' for law enforcement

A story on Innovation Trail reports on a low-cost chemical sensing chip developed by Qiaoqiang Gan, associate professor of electrical engineering, that could test people for cocaine as quickly as a breathalyzer identifies alcohol.

"The way we explore those fundamental features of these nano materials, usually we have to think about what is applications," he said. "Therefore, when we develop some nano structures, I kept thinking of what is the new application. That's why we started to move into the application area. So sensing, drug sensing, chemical sensing is our target."
