Development of a portable smart Glucometer with two electrode bio-electronic test strip patch based on Cu/Au/rGO/PEDOT:PSS.

Today, the importance of blood sugar monitoring in diabetic patients has created a global need to develop new glucometers. This article presents the fabrication of a portable smart glucometer for monitoring blood glucose with high sensitivity. The glucometer employs a bio-electronic test strip patch fabricated by the structure of Cu/Au/rGO/PEDOT: PSS on interdigitated electrodes.

Flexible Bio-Electronic Hybrid Metal-Oxide Channel FET as a Glucose Sensor.

A high-sensitivity flexible field-effect transistor (FET) based glucose sensor is fabricated that can surpass the conventional electrochemical glucometers in terms of sensitivity, limit of detection, and other performance parameters. The proposed biosensor is based on the FET operation with the advantage of amplification which provides a high sensitivity and a very low limit of detection. Hybrid metal oxide (ZnO and CuO) nanostructures have been synthesized in the form of hollow spheres (ZnO/CuO-NHS).

Blood glucose sensing by back gated transistor strips sensitized by CuO hollow spheres and rGO.

In this work, a highly sensitive flexible glucose sensor based on a field effect transistor (FET) has been fabricated. It is shown that the proposed flexible transistor can be used as new non-enzymatic blood glucose test strips. CuO hollow-spheres decorated with reduced graphene oxide have been synthesized using the hydrothermal method.
