“…[220][221][222] Data fusion and fault diagnosis can also help to improve the accuracy and reliability of the exible potentiometric pH sensing arrays based on RuO 2 sensitive electrodes and Ag differential REs. 223 Flexible sensing arrays can also facilitate spatial mapping of wound pH, which can reveal the location and severity of bacterial infections. For example, the simultaneous measurement of multiple sites within one wound region was made possible with an inexpensive exible array (3 cm Â 3 cm) of pH sensors on a palette paper substrate (Fig.…”

“…The synthesized GO was characterized by Raman spectroscopy. Raman spectroscopy is an analytical technique for characterizing the differences between sp 2 and sp 3 hybridization in carbon materials [33]. The Raman spectra of GO are characterized by a D band at approximately 1340 cm −1 and a G band at approximately 1590 cm −1 [34,35].…”

In this study, the potentiometric arrayed glucose biosensors, which were based on zinc oxide (ZnO) or aluminum-doped zinc oxide (AZO) sensing membranes, were fabricated by using screen-printing technology and a sputtering system, and graphene oxide (GO) and Nafion-glucose oxidase (GOx) were used to modify sensing membranes by using the drop-coating method. Next, the material properties were characterized by using a Raman spectrometer, a field-emission scanning electron microscope (FE-SEM), and a scanning probe microscope (SPM). The sensing characteristics of the glucose biosensors were measured by using the voltage–time (V-T) measurement system. Finally, electrochemical impedance spectroscopy (EIS) was conducted to analyze their charge transfer abilities. The results indicated that the average sensitivity of the glucose biosensor based on Nafion-GOx/GO/AZO was apparently higher than that of the glucose biosensor based on Nafion-GOx/GO/ZnO. In addition, the glucose biosensor based on Nafion-GOx/GO/AZO exhibited an excellent average sensitivity of 15.44 mV/mM and linearity of 0.997 over a narrow range of glucose concentration range, a response time of 26 s, a limit of detection (LOD) of 1.89 mM, and good reproducibility. In terms of the reversibility and stability, the hysteresis voltages (VH) were 3.96 mV and 2.42 mV. Additionally, the glucose biosensor also showed good anti-inference ability and reproducibility. According to these results, it is demonstrated that AZO is a promising material, which could be used to develop a reliable, simple, and low-cost potentiometric glucose biosensor.

In this study, a novel potentiometric glucose biosensor based on magnetic beads-Nafionglucose oxidase/graphene oxide/aluminium-doped zinc oxide (MBs-Nafion-GOx/GO/AZO) membranes on a PET substrate with arrayed screen-printed electrodes (SPEs) was proposed. The morphologies, elemental analysis, and surface roughnesses of the sensing membranes were characterized. The sensing parameters of the biosensor were investigated by using the voltage-time (V-T) measurement system, which measured sensitivity, linearity, anti-interference ability, reversibility, temperature effect, and lifetime. A microfluidic device using polydimethylsiloxane (PDMS) was integrated with the V-T measurement system to analyze the response characteristics. The results under static solution and microfluidic flow conditions were compared. The results showed that the average sensitivity and linearity of the biosensor depended on the microfluidic flow rate. The best average sensitivity of the glucose biosensor based on MBs-Nafion-GOx/GO/AZO membranes was 20.35 mV/mM at a flow rate of 15 µL/min.
