Glucose biosensor

In this work, molybdenum disulfide (MoS2) nanorods (NRs) were prepared by a simple hydrothermal method. A sensitive electrochemical glucose biosensor was developed based on the immobilization of glucose oxidase (GOx) on MoS2 NRs modified glassy carbon electrode (GCE).

The present work examıned the use of biochar derived from tea waste as a novel electrode material. For the fabrication of the biochar electrode, suitable amounts of biochar and graphite were mixed with mineral oil for the first time. The electrochemical performance of the biochar-modified carbon paste electrode (BCPE) was measured by various cyclic voltammetric reactions for several redox systems. The factors affecting the electrode kinetics of BCPE surfaces were examined and optimized. The BCPE was applied as transducer in a glucose biosensor.

By using the transfer matrix method (TMM) and numerical simulations, the designs of the sensor based on silicon waveguides are optimized and demonstrated in detail. We applied our structure to detect glucose and ethanol concentrations simultaneously. A high sensitivity of 9000 nm/RIU, detection limit of 2x10-4 for glucose sensing and sensitivity of 6000nm/RIU, detection limit of 1.3x10-5 for ethanol sensing are achieved.

At present, the main field of biosensor applications is still the determination of blood glu‐ cose, as over 90% of all commercial biosensors are developed for diabetes control. However, regardless of the remarkable success in the development of glucose biosensors, there are nu‐ merous other emerging fields to be addressed, particularly the monitoring of environment, healthcare and medical diagnostics.
