Biomolecular Sensing for Cancer Diagnostics Using Carbon Nanotubes

Abstract

A carbon nanotube (CNT) based biosensing approach for cancer diagnostics is described. The CNT based biosensor consists of a nanoelectrode array fabricated using conventional microfabrication techniques. In this array, each nanotube electrode is functionalized with a probe mol. The probe-target interaction is captured through the measurement of electrochem. signals amplified by the use of metal-ion mediators. The interesting properties, nanoelectrode fabrication, testing and characterization of this sensor are discussed. [on SciFinder(R)]
