Abstract: In this study two methods of involving modification of electrodes with gold nanoparticles (AuNPs) was developed, optimized and applied to the detection of histamine in parts per billion levels towards real fish samples. The study implemented a voltammetric platform for the detection of histamine as opposed to the current method of high performance liquid chromatography. The first method involved the modification of commercially available carbon based screen printed electrodes which were then modified using chronoamperometric techniques to deposit AuNPs from the solution onto the electrode surface. The redox capabilities of the unmodified and modified electrodes were studied using histamine standards.
