Ternary transition metal sulfide for Glucose sensing

What is it about?

Blood-glucose measurements are important and necessary to manage diabetes. Most electrochemical commercial glucose sensors use enzymes that are immobilized on the electrode surface. However, enzyme-based glucose sensors require particular operating conditions. In addition, enzyme-based biosensors have poor thermal and chemical stability, as the enzyme is highly sensitive to atmospheric conditions.To avoid these problems, non-enzymatic glucose sensors have recently been developed.Although binary TMDs have already been demonstrated for the abovementioned applications, there is no report on their electrochemical sensing properties, especially in non-enzymatic glucose sensor applications. Thus, the present study explores the non-enzymatic glucose- sensing properties of NiCO2S4 (NCS) nanosheets. NCS nanosheets were directly electrodeposited onto a photolithographically patterned platinum electrode, and the glucosesensing properties studied using cyclic voltammetry and chronoamperometric techniques.
