Abstract

Abstract : A novel amperometric electrode is fabricated using platinum nanoparticle (Pt NP) decorated porous hexagonal boron nitride (h-BN) whiskers. Abstract : A novel amperometric electrode is fabricated using platinum nanoparticle (Pt NP) decorated porous hexagonal boron nitride (h-BN) whiskers. The BN–Pt composite with a mass ratio of BN whiskers to H2 PtCl6 of 1 : 2 exhibits a good amperometric response towards the reduction and oxidation of H2 O2 . This feature allows us to apply it as a bioplatform on which glucose oxidase (GOD) is immobilized through a simple adsorption mechanism for the construction of the glucose biosensor. The developed glucose biosensor showed a fast response time (within 5 s), high sensitivity (6.37 mA M −1 cm −2 ) and a linear range of 0.1–2.7 mM with a detection limit of 14.1 μM (S/N = 3). The biosensor also exhibits good anti-interference ability.
