Comparing the electrochemical performance of pyrolysed photoresist film electrodes to glassy carbon electrodes for sensing applications

Abstract

This paper investigates the comparison of glassy carbon to that of thin carbon films as electrode substrates. It is observed that the modification of the carbon surfaces, via the electrochemical reduction of aryl diazonium salts to the surface, occurs on both substrates in a similar fashion. Subsequent modification of the substrates with the peptide Gly-Gly-His attached to the bound layer, shows that both surfaces can be used in the detection of copper (II) in water solutions and at pH 7.

A Flexible a-SiC-Based Neural Interface Utilizing Pyrolyzed-Photoresist Film (C) Active Sites

“…As one of the most versatile elements in the periodic table, carbon has been incorporated into many device applications [ 19 ]. Since 2000, carbon-based materials, such as carbon nanotubes (CNT) [ 20 ], graphene [ 21 ], glassy carbon (GC) [ 22 ] and pyrolyzed photoresist film (PPF) [ 23 ], have been prominently featured in biomedical device applications and show great potential for mINP applications [ 24 , 25 ]. There are debates on the neurotoxicity of CNT and graphene nanomaterials [ 26 , 27 ].…”

“…In addition, the fabrication processes for graphene and CNT-based mINPs have been demonstrated as overly complex, potentially expensive, and hard to scale reliably. Furthermore, comparing with GC, PPF has a smoother surface and better electrochemical performance [ 22 ]. Thus, in this report, the performance of PPF as a conductive trace, fully encapsulated in a -SiC, was evaluated for mINP electrode applications.…”
