Abstract [en]

We introduce a hybrid two-dimensional nanointerface structure for bioelectronic systems. We fabricated smart hierarchically self-assembled 2D electrobiocatalytic interface system based on the combination of gold nanoparticles doped graphene oxide (GO)-molybdenum disulfide (MoS2) layered nanohybrid, conjugated with poly (N-isopropylacrylamide, PNIPAAm) resulting in GO/AuNPs/MoS2/PNIPAAm interface. Horseradish peroxidase (HRP) was subsequently immobilized on the GO/AuNPs/MoS2/PNIPAAm interface through electrostatic interactions giving GO/AuNPs/MoS2/PNIPAAm/Peroxidase electrobiocatalytic interface system as a platform for electrobiocatalysis reactions for biosensing and bioelectronic applications. The electrobiocatalytic activity of the nanohybrid interface structure was studied using hydrogen peroxide (H2O2) as a model analyte. Cyclic Voltammetry showed diffusion controlled electron transfer properties at the interface. The fabricated bioelectrode exhibits a wide linear response to the detection of H2O2 from 1.57 to 11.33mM, with a detection limit of 3.34mM (S/N=3) and a capacitance of 8.6F/cm(2).
