Herein, a facile approach for shape-controlled gold nanoparticle (AuNP) decorated thionine-MoS2 nanocomposites (AuNP-Thi-MoS2) had been reported by using the synergistic effect of MoS2 and Thi. Thi was not only used as an electrochemical indicator, but also as a reducing agent

The electrochemical activity of graphene is of fundamental importance to applications from energy storage to sensing, but has proved difficult to unambiguously determine due to the challenges innate to fabricating well defined graphene electrodes free from contamination. Here, we report

A quick and selective analytical method was developed for the simultaneous quantitation of 2-methylimidazole, 4-methylimidazole, and 2-acetyl-4-(1,2,3,4-tetrahydroxybutyl)imidazole, which are known to be formed by Maillard reactions. The methodology reported here employs stable-isotope dilution analysis (SIDA) using 4-methylimidazole-d6 and [(13)C6]-2-acetyl-4-(1,2,3,4-tetrahydroxybutyl)imidazole as

Partially blocked electrodes (PBEs) are important; many applications use non-conductive nanoparticles (NPs) to introduce new electrode functionalities. As aggregation is a problem in NP immobilization, developing an in situ method to detect aggregation is vital to characterise such modified electrodes.

Fully-integrated electro-fluidic systems with micro-/nano-scale features have a wide range of applications in lab-on-a-chip systems used for biosensing, biological sample processing, and environmental monitoring. Rapid prototyping of application-specific electro-fluidic systems is envisioned to facilitate the testing, validation, and market translation
