Abstract
In this paper we report on the integration, on a glass substrate, of a microfluidic network with a balanced photodiode constituted by two series-connected amorphous silicon/silicon carbide n-i-p stacked junctions. The photosensor is suitable for detection of small variations of photocurrent in biomedical application. The experiments have been carried out measuring the differential current under a large background light intensity to reproduce realistic operating conditions for a point-of-care analysis system. We have found that the proposed device is able to detect the presence or absence of water flow in the channel. © 2014 Springer International Publishing Switzerland.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
