Novel NO biosensor based on the surface derivatization of GaAs by "hinged" iron porphyrins
A tailor-made, two-component molecular system bound to a GaAs based electronic device has been used to detect nitric oxide (NO) in physiological buffer solutions down to a concentration of 1 ppm (ca. 3 μM). This is made possible because the current through the GaAs changes when NO binds to an iron(III) porphyrin (see picture).
