Carbon nanotubes and nanopipes have been shown to have great potential as cellular probes, for use as nanofluidic devices to transport solutions to or from cells. Making these nanopipes able to sense ...

A new class of materials called Carbon NanoTubes (CNTs) has attracted significant interest for a wide range of engineering applications. These materials look similar to graphitic carbon in structure.

Raman spectroscopy reveals chemically specific information and provides label-free insight into the molecular world. However, the signals are intrinsically weak and call for enhancement techniques.

Carbon nanotubes (CNT) can be considered as graphene which forms a tube instead of a sheet. CNT is considered to be a one-dimensional material composed of a different set of properties than two ...

Carbon nanotube architectures are used in numerous technologies because of their unique attributes. Raman spectroscopy can analyze a variety of carbon nanotube attributes, including tube diameter, ...

We apply immense strain to ultralong, suspended, single-walled carbon nanotubes while monitoring their Raman spectra. We can achieve strains up to 13.7 ± 0.3% without slippage, breakage, or defect ...

Raman imaging techniques are used to obtain information about the molecular vibrations and crystal structure of a sample. Image pixels are used to acquire a complete spectrum, which is subsequently ...
