We have successfully demonstrated the single-walled carbon nanotube (SWNT) network based biosensor using aptamers as the protein recognition site. The single-walled carbon nanotube network was used to improve the uniformity in I-V characteristics. Aluminum was first patterned on the substrate with CVD-grown oxide. Then gold electroless plating and pulse annealing method was employed to reduce a contact resistance. Finally, aptamers were attached on the surface of SWNTs and used as a recognition site of human serum albumin. Carbon nanotube shows that it can be a powerful candidate for the next-generation sensor element for the biological/chemical detection.
