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.
