Nanotechnology based cell-all phone-sensors for extended network chemical sensing

The work presented here is a first ever complete intelligent network chemical sensing system with 1) a compact, low-cost, low-power, high-speed nanosensor array-based detector integrated with 2) a smartphone for detection of chemical threats and transmission of sensor data via cellphone communication system to 3) a network cloud for centralizing the chemical sensing information from 29 phone-sensors at different locations across the country.
