S&M3412 Letter https://doi.org/10.18494/SAM4618 Published: October 12, 2023 An Enhanced Performance of Glucose Biosensor based on TiO2 Nanorod Arrays Decorated with Ag Nanoparticles [PDF] Minghui Chen, Jin Liu, Pengzhao Chang, Shaohui Zheng, and Yong Wang (Received August 18, 2023; Accepted September 28, 2023) Keywords: TiO2 NAs, Ag NPs, Ag NPs-TiO2 NAs/CP electrode, glucose biosensor, sensitive glucose detection
In this study, TiO2 nanorod arrays (NAs) on carbon paper (CP) substrates were prepared via hydrothermal synthesis. Then, Ag nanoparticles (NPs) were deposited on the surface of the TiO2 NAs to enhance the electrocatalytic activity and analysis ability of the electrode for H2O2. Thereafter, the GOx was modified on the surface of the Ag NPs-TiO2 NAs/CP via the cross-linking method for the detection of glucose. The GOx/Ag NPs-TiO2 NAs/CP integrates the functions of the specific recognition of glucose, signal transduction, and signal amplification. In an in vitro test, this GOx/Ag NPs-TiO2 NAs/CP biosensor shows a sensitivity of 0.182 mA mM−1cm−2, which is 6.6-fold of that for the GOx/CP sensor (0.0276 mA mM−1 cm−2). The sensor can transduce the GOx catalyzed reaction into significant current signals within 5 s. The relation between the glucose concentration and the sensitivity to glucose is linear with the correlation coefficient R2 of 0.9996 in the range of 0–0.9 mM, and the detection limit was estimated to be 1.6 μM.
