Figure 2From: Direct patterning of gold nanoparticles using flexographic printing for biosensing applications Schematic diagram showing the functionalisation scheme. The scheme shows the major steps in the functionalisation scheme for AuNPs on carbon electrode. Starting with the printed carbon electrode AuNPs are printed and functionalized with cysteamine, glutaraldehyde and glucose oxidase, also included is a schematic of a fully prepared electrode for biosensing (left).Back to article page
