Abstract

We examined the potential of platinum nanoparticles (PtNP) modified single-walled carbon nanotube (SWNT) hybrid chemiresistive sensor for detection of antigen myoglobin (Mb) in phosphate buffer saline. Protein antibody, Ab-Mb, was covalently immobilized through site specific binding on PtNP attached over SWNT. A concentration-dependent change in the source-drain current of the hybrid device was observed in the range of 0.1-1000 ng ml(-1). The hybrid device response fitted well with the Hill-Langmuir equation with a maximum response of 111.14% and low dissociation constant value (K-d = 19.98 ng ml(-1)), indicating high protein antigen binding affinity at hybrid nanostructure.
