Embedded unit for point-of-care impedance based biosensor readout

Abstract

Bridging the gap between state of the art consumer electronics and bio-analytical setups designed for lab environments, an embedded, miniaturised, stand-alone measurement device is developed. The presented impedance analyser incorporates most of the data communication features present in current-generation smartphones and is specifically optimised for low-frequency impedance based biosensor readout. The compact unit operates fully stand-alone with a touchscreen. Its functionality was tested and verified. In this work the unit is tested by using a biomimetic sensing device for the detection of L-nicotine. The combination between the handheld, embedded design of this specialised measurement equipment and a sensor layout fine-tuned for specific applications could mean significant advances in point-of-care systems.
