Magnetically assembled multiwalled carbon nanotubes on ferromagnetic contacts

Article Abstract:

A method to assemble carbon nanotubes is demonstrated from solution on ferromagnetic contacts using a commercially available permanent magnet. By modifying one end of vertically grown multiwalled carbon nanotubes (MWNTs) with a ferromagnetic material, it is shown that it is possible to direct individual carbon nanotubes with a weak external magnetic field to assemble on ferromagnetic metal electrodes and create ohmic contacts.

Poly-L-lysine fictionalization of single-walled carbon nanotubes

Article Abstract:

Single-walled carbon nanotubes (SWNTs) are covalently functionalized with biocompatible poly-L-lysine, which is useful in promoting cell adhesion. SWNTs play an important role as connectors to assemble the active amino groups of poly-L-lysine, which provides a relative soft environment for further derivation.
