Abstract

In this paper we describe a single wall carbon nanotube (SWNT) based biological sensor for the detection of bio molecules like Streptavidin and IgG. SWNT have been employed for two types of sensing mechanisms. Firstly, the changes in the electrical conductance of the carbon nanotube matrix on non covalent binding of the biomolecules to the side walls of the carbon nanotube and secondly, quantification of mass uptake of the matrix on biomolecule incubation are presented. Both sensing mechanisms exhibited consistent and highly sensitive responses. Biomolecular immobilization on the carbon nanotube surface was monitored by Atomic Force Microscopy.
