The Electrochemistry of a Gelatin Modified Gold Electrode

open access: yesInternational Journal of Electrochemical Science, 2011
Abstract: This paper discusses the electrochemical behaviour of gelatin coated gold electrodes in physiological pH conditions in a potential window −1.5 till 1.0 V vs SCE by performing cyclic voltammetry. A comparison is made between gelatin A and gelatin B, which have respectively a positive and a negative net charge at physiological pH.
