Platinum electrodes for NO detection. A) i) Platinum pseudo-electrode (500 μm) and platinum working electrode [250 μm] encapsulated with epoxy in a flangeless fitting; ii) Zoomed micrograph of the platinum black modified platinum working electrode; B) Bar graph comparing the signal for NO [190 μM] with a bare Pt electrode verses the Pt/Pt-black modified electrode; C) Amperogram of reproducible 190 μM NO injections over the Pt/Pt-black electrode.
