Applied Nanodetectors Limited has developed a sensor array platform than can be configured and detect multiple species. This sensor array can be integrated with mainstream semiconductor processes and manufactured at high volume. These sensors arrays have all the attributes of nano technology based sensors, high sensitivity, small size and low power consumption. These arrays can be used for chemical, bio-sensors and gas sensors. They offer significant performance advantages for real time monitoring applications such as point of care diagnostics (POC) and the detection of VOCs in headspace analysis of biological specimens. One particular exciting application of these sensor arrays is breath analysis, a non-invasive process whereby small quantities of volatile organic compounds can be detected in human breath, and they can form a fingerprint that can be used for early disease detection and diagnosis.
