Abstract:

Flower-like MoS2 micrometer material was successfully synthesized by hydrothermal reaction, which was then used to prepare the glucose biosensor. The performance of the prepared glucose biosensor was examined. Results indicated that as-synthesized MoS2 is flower-like structure in good crystallinity at ~3.6 μm in length with specific surface area 9.646 m2/g. The biosensor with MoS2 electrode has a high responsivity of glucose, due to good electrocatalytic activity and small electrical impedance of MoS2. Glucose detection revealed that oxidation peak current showed a good linear relationship with glucose concentration in the range of 0~20 mmol/L with a correlation coefficient (R) 0.9653. The sensitivity is 262 μA•L/mmol.
