The nanowire sensor works by detecting the activation of T cells by specific bacterial, viral or even cancer antigens. This activation produces acid, which generates a tiny current in the nanowire electronics, which can then be detected. The nanowire sensor is highly sensitive, with the ability to identify a single disease antigen, even with the presence of substantial background ‘noise’ from general immune system cells. The inventors envisage this technology could be used to make an iPod-like device with changeable cards to detect or diagnose disease in point-of-contact diagnostics.
