Scientists have developed
a low-cost chemical sensing chip that could test people for cocaine as quickly
as a breathalyser identifies alcohol. Such a technology has long been on the
wish list of police officers and others looking to monitor drug use and curb
dangerous driving, said researchers from the University at Buffalo in the US.
The chip could be
integrated into a hand-held, portable device for detecting drugs in biological
samples such as blood, breath, urine or spit. “Currently, there is a great
demand for on-site drug testing,” said Qiaoqiang Gan, an associate professor in
the University at Buffalo. “The high-performance chip we designed was able to
detect cocaine within minutes in our experiments. It is also inexpensive: It
can be produced using raw materials that cost around 10 cents, and the
fabrication techniques we used are also low-cost,” said Gan. “In the future, we
are hoping to also use this technology to detect other drugs, including
marijuana,” he said.
