Nanotechnology to Enhance Electron Transfer

This lecture explores the application of carbon nanotubes (CNT) in enhancing electron transfer for biosensors. Topics covered include the electrochemistry of CNT, their electrical conductivity, and their role in improving electron transfer at the bio/sample interface. The lecture delves into the integration of CNT in nano-bio-sensors, different deposition techniques, and their impact on sensitivity and detection limits. It also discusses the Nernst effect, layering effect, and Cottrell effect with CNT, emphasizing their contributions to redox reactions efficiency. The presentation concludes with insights into electron emission by CNT, focusing on the tip and side-wall contributions.
