“Hydrogen Ion Implanted Enzyme Free Clay Based Cholesterol Sensor”


Updated about 1 year ago

Abstract

Ion irradiation experiments were performed on Laponite-Montmorillonite/Indium Tin Oxide (L-MMT/ITO) films using 20 keV H2+ ion beam with variable fluence ranging from 1012 – 1016ions/cm2and the electrochemical profiling of these irradiated electrodes were done using Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform Infrared spectroscopy (FTIR) were used for pre and post-irradiation morphology study and binding analysis. FTIR spectroscopy indicated the implantation of low-energy H2+ions resulting in the formation of new bonds. The enhanced cholesterol sensitivity of irradiated films uptofluenceof1013 ions/cm2was observed due to morphological changes taking place in L-MMT films. Close to 20% enhancement in cholesterol sensitivity was noticed, when the ion fluence was ≈ 1013 ions/cm2. The sensitivity for cholesterol detection of the L-MMT electrode formed through H2+ ion implantation clearly exhibited a strong dependence on the fluence of the ion beam. The radiation-induced enhanced sensitivity can be proposed as a platform for development of a more effective enzymes-free strip sensor.
