Carbon nanotubes were used in medical sciences especially in drug delivery system and cancer therapy. In this study; we functionalized carboxylated single wall carbon nanotubes(SWNT-COOH) with 2-en 4-hydroxy cyclo 1-octanon. Synthesized sample was characterized by FT-IR, Raman spectroscopy, SEM, TGA and cellular investigations. The results showed well formation of SWNT-Ester .Cell viability assay results and microscopic observationsdemonstrated that cancerous cells killed in the sample. The synthesized sample can be used as a toxic material for cancer therapy
