    The proposed system provides a fast, simple and cheap method for on-site determination of protein concentration in aqueous solutions. This paper explains how the ion-step method is performed on Ta2O5 ISFETs that are incorporated in a disposable chipcard. An external pump mechanism (stamps) eliminates the need for micro-machined components on the chipcard.
