Resistance-based biosensor of Multi-Walled Carbon Nanotubes.

Resistance-based biosensor of Multi-Walled Carbon Nanotubes. J Immunoassay Immunochem. 2015;36(2):142-8 Authors: Kolosovas-Machuca ES, Vera-Reveles G, Rodríguez-Aranda MC, Ortiz-Dosal LC, Segura-Cardenas E, Gonzalez FJ Abstract Multi-Walled Carbon Nanotubes (MWNTs) are a good choice for resistive biosensors due to their great resistance changes when immunoreactions take place, they are also low-cost, more biocompatible than single-walled carbon nanotubes, and resistive measurement equipment is usually not expensive and readily available. In this work a novel resistive biosensor based on the immobilization of an antigen through a silanization process over the surface of Multi-Walled Carbon Nanotubes (MWNTs) is reported. Results show that the biosensor increases its conductivity when adding the antigen and decreases when adding the antibody making them good candidates for disease diagnosis.
