Glucose sensing performance of PAN: β-rhombohedral borophene based non-enzymatic electrochemical biosensor

Abstract

In this study, centrosymmetric β-rhombohedral crystalline structured borophene was prepared by the physical exfoliation method. Hexagonal morphology of Borophene with 0.41 nm lattice spacing was observed. PAN: β Borophene nanocomposite was prepared by sonication of PAN and β borophene. PAN: β Borophene was observed in bunch fringes nanomorphology. PAN-based and PAN: β-Rhombohedral Borophene-based non-enzymatic electrochemical biosensors were prepared to scrutinize the glucose-sensing performance. PAN: β-Rhombohedral Borophene provided a high charge transfer mechanism to sense glucose more sensitively at room temperature. The PAN: β-Rhombohedral Borophene-based biosensor has a sensitivity of 8.43 μA mM−1 cm−2 in a voltammetry cycle of 1 min. The limit of the detection of the PAN: β-Rhombohedral Borophene-based biosensor is 0.099 mM. The prepared non-enzymatic electrochemical biosensor based on PAN: β-Rhombohedral Borophene is the first reported PAN-based non-enzymatic biosensor to sense glucose. The biosensor has low-cost, portable, has good stability, short response time, and high sensitivity features.
