Flexible biological sensors based on carbon nanotube films

Abstract

This paper presents the technique of forming flexible liquid sensors for biological applications based on carbon nanotube networks. We bend structures with a radius of curvature of 5 mm and the resistance change is no more than 8–10%, keeping the overall properties of the conductive coatings developed during multiple bends. We demonstrate the possibility of determining thrombin when biosensor structures are immobilized by specific aptamers.
