With the oxidation catalyzed by IDO, tryptophan is hydrolyzed and kynurenine is generated, which may induce the further immobilization of dithiobis [succinimidylpropionate]-modified Pt nanoparticles onto the electrode surface. Since Pt nanoparticles can electrochemically catalyze the reduction of H2O2, the produced electrochemical signal is then correlated with the enzyme activity of IDO. 13 Schematic representation of the electrochemical analysis of IDO activity. Reprinted from Ref. [102], Copyright 2010, with permission from Elsevier Graphene is a newly developed advanced two-dimensional nanomaterial, discovered in the year of 2004 [103].
However, after the phosphorylation catalyzed by protein kinase A takes place, the SAM becomes loose. Due to the existence of phosphate groups, [Ru(NH3)5Cl]2+ probes then get close to the electrode surface by electrostatic interaction, making the detection system lies in the “On” state. 11 is the differential pulse voltammograms of [Ru(NH3)5Cl]2+ to show the two states of the detection system. It also reveals that this detection system can be reused for many times without significant loss of detection precision.
