Covalently Functionalized Hexagonal Boron Nitride Nanosheets : Efficient Electrochemical Sensor Biosystems

In recent years have seen a surge of increased interest in the exfoliation of boron nitride (h-BN) due to its exciting electrical, thermal,photonics mechanical properties and sensing. Several approach to have emerged describing the exfoliation,functionalized and solubilization of h-BN. In this study, we report on a straightforward approach to modify the surface and its application as a new type of biomedical applications. The prepared product is structurally characterized by FTIR spectroscopy, field emission (FESEM), TGA technique, XPS spectrum, and BET surface area measurements. Nano- composites were immobilized on electrodes to detect the glucose,L-cysteine in buffer medium by cyclic voltammetry (CV), square wave voltammetry (SWV), and impedance spectroscopic (EIS). potential application of the covalent functionalization, cheap precursors, biodegradability and multifunctionality of high-performance composites boron nitride , they could be used for a wide range of the future biomedical applications.
