Dopamine detection using mercaptopropionic acid and cysteamine for electrodes surface modification

cerevisiae cells at pH 7.2, the obtained value of R(ct) showed over 560 percent from the value obtained on the same thiol-modified electrode [ 8 , 9 , 10 , 11 , 12 ]. The main objective of this presented work is to give a better understanding of the comparative study of targeted dopamine detection with two modifications for the surface of Au electrodes i.e., (1) cysteamine and (2) MPA for thermally bonded and ultrasonically welded microfluidic chips, respectively. The influence of both bonding techniques along with the selection of optimized tubing for the fabricated
