“…After biofuncionalization, the developed nanostructures provided good fluorescence response for captured dye-labeled target protein molecules [89]. Non enzymatic glucose detection was proposed by Tarlani et al [93]. The ZnO surface functionalization was achieved through special growth conditions in the presence of aminoacids.…”

“…Regarding to a progress in nanotechnology and material science, new technological methods have been developed to fabricate nanostructured ZnO templates with high surface area and advanced properties for biosensors. Nanostructured ZnO films have been widely used as template in electrochemical biosensors before demonstrating good sensitivity and low detection limit [30,39,55,88,90,[92][93][94], while ZnO nanowires, nanorods etc. have been widely used recently as the sensing element in FET biosensors [29,33,87].…”

Abstract. ZnO nanostructures were formed via a hydrothermal reaction mechanism between simple anionic (ammonia or sodium hydroxide) and cationic (zinc acetate dehydrate) precursors without using any organic templates. E ects of the reaction conditions, including the initial solution pH, type and concentration of the anionic and cationic precursors, and the reaction time and temperature, on the nanostructure particle size and morphology were investigated. The nanostructures formed were analyzed by powder X-ray di raction, energy dispersive X-ray analysis, and scanning electron microscopy. According to the results, the morphology of the nanostructures is highly pH-dependent. Needlelike nanostructures were formed using ammonia at initial solution pH value around 9, but plate-like nanostructures were formed using NaOH at pH value around 13, regardless of the reaction time or temperature. The precursors concentration could not be considered as an independent parameter per se as it consequently changes the reaction medium pH, which a ects the morphology in turn. In general, increasing the reaction time and temperature increased the mean particle size of the nanostructures with no signi cant change in their morphology. It was found that the nanostructure morphology changes from nanoneedle to star-like at higher addition rates of ammonia.

This work investigates the capabilities of a platform for nonenzymatic glucose sensing employing a novel 3D printed three‐electrode mask‐embedded design. A reservoir‐on‐mask has been fabricated for smart sample insertion to avoid spillage. Working and counter silver electrodes are modified with three different material combinations such as graphene oxide (GO), poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and GO + PEDOT:PSS, and their performance comparison is demonstrated. It is observed that the GO + PEDOT:PSS modification shows 94.57 and 71.01% higher sensitivity than GO and PEDOT:PSS, respectively, including a higher linearity compared to its counterparts. Glucose concentrations ranging from 50 to 300 mg dL−1are detected by employing cyclic voltammetry and electrical impedance spectroscopic technique. Herein, a significantly high sensitivity of 18.8 μAmM−1 cm−2and low limit of detection ≈ 0.4 mM has been achieved for the proposed sensor. The 3D printed mask structure provides 75% higher sample retention ability, greater reliability in terms of sample placement in the sensor and improved test performances. The proposed sensor can provide a stable and large‐scale deployable solution to future biosensing platforms.
