“…[14] Additionally, chemical surface modification is an effective technique to control the reactivity of the electrode or to characterize it with specific functional groups, thereby facilitating the immobilization and detection of diverse biomolecules such as antibodies, nucleic acids, enzymes, etc. [15] In order to improve the sensing performance, several methods are developed to modify the surface, including: electrochemical deposition, physical or chemical vapor deposition (PVD or CVD), silane chemistry, click chemistry, diazonium chemistry, self-assembly, etc. [16] Since it was first reported by Pinson et al in 1992, diazonium chemistry has been interesting to researchers because of its "convenient, economical and stable" characteristics.…”

In this study, a surface functionalization approach by covalent grafting of an organic thin film containing hydroxyl groups on TiN surface via electroreduction of diazonium salts "4‐(2‐hydroxyethyl)benzenediazonium salt" is presented. Cyclic voltammetry procedures were carried out at the potential ranges of ‐0.8 V~0.5 V (vs Ag/AgCl) with varying numbers of potential cycles (i.e., 5, 25, and 50 cycles) in order to study the thickness of modification layer. Then, the electrochemical properties, surface morphology, and chemical structures of the sample before and after modifications were investigated via multiple characterization techniques, such as cyclic voltammetry (CV), atomic force microscopy (AFM), scanning electron microscope (SEM) and X‐ray photoelectron spectroscopy (XPS), etc., thereby confirming the successful grafting of hydroxyl groups onto the TiN surface. The experiments on DNA synthesis aimed to explore the potential of modified TiN electrode as a novel platform for DNA data storage applications and the corresponding proof‐of‐principle was accomplished by the process of coupling Cy3‐phosphoramidite. Finally, the experiments were successfully reproduced on the randomly selected sites of the modified TiN microarray chips demonstrating the potential of technical protocol to extend applications in future bioelectronic devices, such as bio‐sensing, high‐throughput DNA synthesis, and molecular manipulation.
