Atomic-Scale Detection of Organic Molecules Coupled to Single-Walled Carbon Nanotubes

摘要

Functionalized carbon nanotubes(f-CNTs)bearing organic molecules and biomolecules show strong potential in biological and biomedical applications.Suitable covalent functionalization of single-walled carbon nanotubes(SWNTs)can tailor critical properties such as solubility in solvents including water,which is crucial for biological applications.Bulk measurements(Raman,IR,UV)are commonly used to characterize modified SWNTs;however,these do not provide direct evidence of the attachment of individual molecules.
