“…The shelf life studies of the bioelectrode shows that it retains more than 90% of activity even after 20 weeks as shown in Supplementary Figure 6. The enhanced sensing response characteristics are attributed to the preparation of a highly stable and biocompatible Cu implanted SnO 2 thin film matrix in the present study [20][21][22][23][24][25][26][27][28].…”

A reagentless uric acid biosensor has been realized using Copper implanted tin oxide thin film (Cu:SnO 2 ) based matrix. The biosensing characteristics of implanted matrix have been studied using the electrochemical impedance spectroscopy and cyclic voltammetry. The prepared matrix (Cu:SnO 2 ), because of the presence of Cu, possess redox properties so that the electron transfer from enzyme to the electrode could be accomplished without using any external mediator in the electrolyte. The developed uric acid biosensor exhibits a high sensitivity of about 0.93 mA/ mM and a linear variation in current response over a concentration range from 0.05 to 1.0 mM of uric acid besides high shelf life (~20 weeks). The Michaelis-Menten kinetic parameter (K m ) is found to be relatively very low (0.12 mM), which indicates the high affinity of the fabricated bioelectrode towards the uric acid (analyte). The results highlight the importance of implanted Cu:SnO 2 thin film as an attractive matrix for the realization of reagentless biosensors towards uric acid.

“…Thin nonconducting POAP films synthesized in neutral media are also employed as protective layers for biosensor applications. In general, POAP films are simultaneously synthesized with different electroactive materials such as, hemoglobin, quinhydrone, carbon nanotubes, prussian blue, and other polymers such as poly(o-phenylenediamine) and polypyrrole, which act as electron mediators [18,23,[28][29][30][31][32][33][34][35][36][37], to build different biosensors. POAP is also widely used as Figure 11: IR spectra of (a) electrochemically prepared POAP, (b) 3-aminophenoxazone [10].…”

This review, which is divided into three parts, concerns electrochemical synthesis, spectroscopic characterization, and formation mechanisms of poly(o-aminophenol) (POAP) film electrodes. The first part of this review is devoted to describe the electropolymerization process of o-aminophenol on different electrode materials and in different electrolyte media by employing both potentiodynamic and potentiostatic methods. The second part refers to spectroscopic studies carried out by different authors to both, identify the products of the o-aminophenol electrooxidation and elucidate the chemical structure of poly(o-aminophenol) film electrodes. The third part shows the different mechanisms formulated to interpret the POAP films formation from both acid and basic solutions of o-AP. Also, some electrochemical and spectroscopic data which allowed to propos the corresponding formation mechanisms, especially in basic media, are described.
