A Sensitive Potentiometric Biosensor Using MBs-AO/GO/ZnO Membranes-Based Arrayed Screen-Printed Electrodes for AA Detection and Remote Monitoring

Investigation of Flexible Arrayed Lactate Biosensor Based on Copper Doped Zinc Oxide Films Modified by Iron–Platinum Nanoparticles

“…The response time is defined as the time required for the output voltage to change from its initial state to 95% of the steady state after immersing the sensor in the test solution [ 22 , 23 ]. In this study, the lactate biosensor was immersed in the PBS solution.…”

An EGFET Based Common Source Amplifier as a Low-Frequency Instrumentation Amplifier for Sensitivity Measurement on RuO2 Lactic Acid Biosensor

“…The concentrations of these interfering substances were the same as that in the human body [46]. The biosensors are required to detect specific analytes.…”

Review—Bio-Nanosensors: Fundamentals and Recent Applications

“…For example, a sensitive potentiometric ascorbic acid (AA) biosensor was introduced in Ref. 170 (Fig. 13).…”

“…13). It uses a magnetic beadsascorbate oxidase/graphene oxide/zinc oxide (MBs-AO/GO/ZnO) membrane-based screen-printed electrode to improve sensitivity, Silver layer acts as the reference electrode and conductive wires, the ZnO layer is used as the sensing matrix, the GO layer increases the number of surface active site, MBs provides the high surface to volume ratio for enzyme immobilization onto the membrane and AO is used as the biometric layer for AA catalysis 170 Reprinted with permission from Creative Commons Attribution 4.0. selectivity and LOD for AA, in comparison to other AA sensor models. Recently, Silva et al reported the use of a paper-based strip electrode in a label-free potentiometric immunosensor for Salmonella typhimurium detection, showing two different immunosensig interfaces assembled on the electrode surface to control an ionic flux through a carboxylated PVC membrane.…”
