Hydrogen peroxide (H 2 O 2 ) is well-known oxidizing, bleaching agent and also one of the significant by-products of diverse regulating biological processes. It has been recognized as a threat in the progression of atherosclerosis, renal disease, ageing and other diseases. Hence, determination of H 2 O 2 in trace levels in biological samples is of great importance. This article briefly reviews the electrochemical detection method for hydrogen peroxide sensing, including the nanomaterial based enzyme-containing and non-enzymatic biosensor. The biosensor can achieve microscopic detection of hydrogen peroxide. It also discusses the performance and future prospects of the electrochemical H 2 O 2 biosensor.

“…MnO 2 , an important transition metal oxide, has been extensively used in rechargeable batteries [19], supercapacitors [20,21], electrocatalysis [22,23], and sensors [24][25][26][27][28], owing to its prominent advantages such as cheapness, low toxicity, and excellent electrocatalytic performances. Moreover, the electrochemical performance can be tailored by tuning the morphologies of nano-MnO 2 [25].…”

“…Moreover, the electrochemical performance can be tailored by tuning the morphologies of nano-MnO 2 [25]. However, the poor electrical conductivity has hindered its broad applications in electrochemical sensors, due to the semiconductor property of itself [26]. Hence, much effort has been devoted to composite or hybrid nano-MnO 2 with conductive components, aiming to enhance electrical conductivity, decrease charge transfer resistance, and eventually improve sensing performances [20,21,29].…”

“…In recent years, MnO 2 -graphene nanocomposite modified electrodes have been widespread in electrochemical sensors. For example, Wu and co-workers developed a non-enzymatically catalyzed H 2 O 2 sensor based on a MnO 2 /reduced graphene oxide nanoribbons composite modified electrode, which exhibits excellent electrochemical performance and high precision, as well as good selectivity, reproducibility, and stability [26]. Mahmoudian et al constructed a H 2 O 2 sensor based on MnO 2 nanotubes/reduced graphene oxide nanocomposite modified glassy carbon electrode, and the charge transfer resistance reduced significantly [24].…”

Abstract:The morphology or shape of nanomaterials plays an important role in functional applications, especially in the electrochemical sensing performance of nanocomposites modified electrodes. Herein, the morphology-dependent electrochemical sensing properties of MnO 2 -reduced graphene oxide/glass carbon electrode (MnO 2 -RGO/GCE) toward dopamine detection were investigated. Firstly, various morphologies of nanoscale MnO 2 , including MnO 2 nanowires (MnO 2 NWs), MnO 2 nanorods (MnO 2 NRs), and MnO 2 nanotubes (MnO 2 NTs), were synthesized under different hydrothermal conditions. Then the corresponding MnO 2 -RGO/GCEs were fabricated via drop-casting and the subsequent electrochemical reduction method. The oxidation peak currents increase with the electrochemical activity area following the order of MnO 2 NWs-RGO/GCE, MnO 2 NTs-RGO/GCE, and MnO 2 NRs-RGO/GCE. The spatial models for MnO 2 NWs, MnO 2 NTs, and MnO 2 NRs are established and accordingly compared by their specific surface area, explaining well the evident difference in electrochemical responses. Therefore, the MnO 2 NWs-RGO/GCE is selected for dopamine detection due to its better electrochemical sensing performance. The response peak current is found to be linear with dopamine concentration in the range of 8.0 × 10 −8 mol/L-1.0 × 10 −6 mol/L and 1.0 × 10 −6 mol/L-8.0 × 10 −5 mol/L with a lower detection limit of 1 × 10 −9 mol/L (S/N = 3). Finally, MnO 2 NWs-RGO/GCE is successfully used for the determination of dopamine injection samples, with a recovery of 99.6-103%. These findings are of great significance for understanding the relationship between unlimited nanoparticle structure manipulation and performance improvement.

Abstract. Thin-film hydrogen peroxide vapor sensors made from Co-doped SnO 2 and La-doped ZnO were manufactured using the high-frequency magnetron sputtering method. Thicknesses of deposited doped metal oxide films were measured and their morphology was investigated. The gas sensing characteristics of the prepared sensors were measured at different concentrations of hydrogen peroxide vapors and different operating temperatures of the sensor. It was found that both sensors made from doped metal oxides SnO 2 and ZnO exhibit a sufficient response to 10 ppm of hydrogen peroxide vapors at the 200 and 220 • C operating temperature, respectively. It was established that the dependencies of the response on hydrogen peroxide vapor concentration have a linear character for prepared structures at the 150 • C operating temperature and can be used for determination of hydrogen peroxide vapor concentration.
