TL;DR: The Au-ZrO2-GNs/GCE nanocomposite sensor showed excellent accuracy and reproducibility for detection of MP in Chinese cabbage samples, providing a new method for efficient pesticide detection in practical applications.

TL;DR: The present novel GECT sensor could act as a desirable practical platform for highly sensitive detection of nitrite in the food and environmental fields and showed good anti-interference performance toward common interfering ions and stable performances.

TL;DR: In this article, a novel graphene electrochemical transistor (GECT) based on zirconia/reduced graphene oxide (ZrO2/rGO) nanocomposites functionalized gate electrode and graphene as channel was successfully designed and fabricated for highly sensitive detection of methyl parathion (MP).

TL;DR: In this paper, a novel graphene electrochemical transistor (GECT) for the detection of methyl parathion (MP) was successfully fabricated for the first time, where a single layer of graphene was covered between the source and drain electrodes by the wet transfer method to act as channel for the transistor, considering the special affinity of ZrO2 nanoparticles toward phosphate group and electrocatalytic ability of Au nanoparticles.

TL;DR: This work demonstrates an effective route for non-invasive glucose testing in practical clinical diagnosis by using nonenzymatic, solution-gated graphene transistor devices.
