Characterization of a tamoxifen-tethered single-walled carbon nanotube conjugate by using NMR spectroscopy.

We report the synthesis and characterization of a tamoxifen-tethered single-walled carbon nanotube (SWCNT) conjugate, in which tamoxifen is covalently attached to the single-walled carbon nanotube via oxidation and esterification reactions for the first time. The functionalized SWCNT derivative was characterized by using spectroscopic techniques: IR, UV-vis, Raman, and (1)H NMR Spectroscopy. The attachment of the drug tamoxifen to SWCNTs is analogous to the gold conjugate, which provided an endocrine treatment for breast cancer.
