Abstract
Remarkable potential has been observed for carbon nano tubes (CNTs) due to structural, mechanical, electrical, and thermal properties and its application as sensing material in pressure, flow, thermal, gas, optical, mass, position, stress, strain, chemical, and biological sensors. CNTs present high stability on its unique structure, only few concentrated acids are capable of breaking the bonds between carbon atoms. Therefore, functionalized multiwall (MW) CNTs have been used for the fabrication of low cost immunosensor based on pencil graphite (Grp). MWCNTs have been covalently immobilized onto pencil graphite (6H, 2mm ? 5mm) using octadecanthiol. Immunosensor has been fabricated by covalently immobilizing anti-BSA (Ab) using aniline as linking agent. Fabricated Ab-MWCNTs-Grp immunoelectrode has been characterised using cyclic voltammetry, square wave voltammetry and Fourier Transfor InfraRed spectrocospy. Fabricated immunosensor Ab-ANI-MWCNTs-Grp has been successfully able to detect BSA using square wave voltammetry. The fabricated immunoelectrode is found to be highly specific for BSA and did not show any non specific binding with other other protein such as albumin. The excellent performance of the immunoelectrode can be attributed to large surface-to-volume ratio, low cost, conductivity and good biocompatibility of aniline leading to enhanced the antibody immobilization and improved direct electron transfer between the surface and MWCNTs-Grp matrix of electrodes.
