ABSTRACT:
The present invention is directed to iron sensors. Immobilized in close proximity of the potential or pH measuring surface of a proton sensing device, minute quantities of an iron chelator such as siderophores or transferring cause detectable variation of the potential or pH upon the binding of iron. The sensing devices for measuring this change in potential or pH include the iron chelator-modified ion-selective field effect transistors (IC-ISFET) and/or pH indicator papers of the present invention.
