Abstract:
This study presents the results of the development and integration of reduced graphene oxide coated with gold nanoparticles and Prussian blue (rGO-AuNP-PB). The coating enhances the LIG electrode conductivity and provides overall catalytic activity improvement. Incorporation of bovine serum albumin (BSA) and glutaraldehyde (Glu) further improved the overall lactate sensor stability. Through experimentation and optimization, we were able to demonstrate significant improvements in the sensitivity and isolation of the lactic acid detection resulting from the improved electrocatalytic performance of the nanocomposite material. Further optimization was achieved through the application of capillary array geometry opposed to traditional collection design geometry.
