Abstract
Point of care testing of biomolecule levels in patients blood or urine is a key future application especially for de-centralized concepts of modern healthcare. One of the discussed platform solutions where remarkable sensitivities were reported by many groups in the field are arrays of silicon nanowire sensors. The miniaturization of classical ion-sensitive field-effect transistor (ISFET) devices into state-of-the-art nanobiosensors is targeted by many researchers nowadays. The ultra-low power consumption of silicon nanowire devices compared to their much larger ISFET counterparts holds great promise for portable devices. However, besides a remarkable sensitivity resulting from the miniaturization the researchers also buy in huge cross-sensitivities to side parameters such as temperature variations, pH changes and ionic changes in the test solutions. This contribution addresses some of these issues and suggests possible implications for the design of robust, portable
solutions for the future healthcare market.
