Modification of carbon nanotube’s dispersion using cetyltrimethyl ammonium bromide (CTAB) as cancer drug delivery

Abstract

Cancer is a disease that causes many deaths globally. Cancer treatments have side effects that can danger the human body. Carbon nanotube (CNT) becomes drug (anti-cancer) delivery towards cancer cells that have been targeted. Yet, CNT tends to aggregate. It could be overcome by functionalization (modification) of CNT using Cetyltrimethyl Ammonium Bromide (CTAB). The variations we use were CNT-CTAB with a dose of CNT 100 mg and CTAB varied between 80, 90, 100, 110, and 120 mg. There were several stages of CNT modification process: dispersion, filtration, washing, and drying. The optimum condition obtained was on CNT-110 mg CTAB because it could be dispersed up to 70 hours better than pure CNT, Zeta Potential (ZP) ≥16 mV, and absorbance Uv-vis 1.05. Both the ZP value and the absorbance of Uv-vis showed the CNT dispersion modified to be better than the pure CNT. Furthermore, SEM-EDX did not produce structural damage to CNT modified surfaces, the percentage of the mass of Oxygen (O) elements as characteristic of increased hydrophilic properties, and Ni elements as toxic impurities become reduced. FTIR spectrum results showed the highest intensity occurred at CTAB CNT-110mg at 1221 m-1. This strong C-N vibration interaction suggests that CNTs CNT modification become readily dispersed in water.Cancer is a disease that causes many deaths globally.
