Scientists have invented a bio- sensor technology - known as a lab on a chip - that could be used in hand-held or wearable devices to monitor health and exposure to dangerous bacteria, viruses and pollutants.
"This is really important in the context of personalised medicine or personalised health monitoring," said Mehdi Javanmard, an assistant professor at Rutgers University-New Brunswick in the US. "We are talking about platforms the size of a USB flash drive or something that can be integrated onto an Apple Watch, for example, or a Fitbit," said Javanmard.
The technology, which involves electronically barcoding microparticles, giving them a bar code that identifies them, could be used to test for health and disease indicators, bacteria and viruses, along with air and other contaminants.
