Overview
The present invention relates to a novel capacitive immunosensor based on protein conjugate Ab-Vc coated onto ant-TiO2-RGO/ITO nanohybrid for estimation of Vibrio cholerae. This BSA/Ab-Vc/antTiO2-RGO/ITO immunoelectrode offers excellent detection range 10 ng/ml to 450 ng/ml, higher sensitivity of about 21.8 x10-3 µF/ng ml-1 cm-2 and better regeneration accuracy of about 95%.
