Sensitive Electrochemical Detection of Bioactive Molecules (Hydrogen Peroxide, Glucose, Dopamine) with Perovskites-Based Sensors

Ratiometric electrochemical detection of hydrogen peroxide and glucose.

Hydrogen peroxide (H2O2) detection is of high importance as it is a versatile (bio)marker whose detection can indicate the presence of explosives, enzyme activity and cell signalling pathways. Herein, we demonstrate the rapid and accurate ratiometric electrochemical detection of H2O2 using disposable screen-printed electrodes through a reaction-based indicator assay. Ferrocene derivatives equip...

Nanomaterial-Based Electrochemical Hydrogen Peroxide Biosensor

Hydrogen peroxide (H2O2) 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 H2O2 in trace levels in biological samples is of great importance. This article briefly reviews the ele...

Biosynthesis of Silver Nanoparticles Using Leaves of Acacia Melanoxylon and their Application as Dopamine and Hydrogen Peroxide Sensors

In this work, we described a cost-effective and environmentally friendly technique for green synthesis of colloidal silver nanoparticles from aqueous extract of fresh leaves of Acacia melanoxylon and its application as a dopamine and hydrogen peroxide sensor. The prepared silver nanoparticles were characterized by UV-Visible absorption spectroscopy, X-ray diffraction (XRD), scanning electron mi...

Sensitive Nonenzymatic Electrochemical Glucose Detection Based on Hollow Porous NiO

Transition metal oxides (TMOs) have attracted extensive research attentions as promising electrocatalytic materials. Despite low cost and high stability, the electrocatalytic activity of TMOs still cannot satisfy the requirements of applications. Inspired by kinetics, the design of hollow porous structure is considered as a promising strategy to achieve superior electrocatalytic performance. In...
