Optical Tracking of Multi-walled Carbon Nanotubes by Attaching Functionalized Quantum Dots

Abstract

Functionalized quantum dots have been successfully attached to multi-walled carbon nanotubes over carbodiimide-assisted coupling. Characterization in a transmission electron microscope shows the quantum dots are attached mainly at the opened tips and defect sites on the side-walls of nanotubes, suggesting the covalent nature of the bonding and high… (More)
