冷冻干燥法制备碳纳米管/微管蛋白杂化材料

hrough the freeze drying mathod，single-walled carbon nanotube was combined with the microtubules protein and synthesized the hybrid material- carbon nanotubes/microtubules protein, which was combined with paclitaxel and then carbon nanotubes/microtubules protein/paclitaxel composite materials was composed finaly. Infrared spectrometry (IR), field emission, atomic force microscope (AFM), Raman spectroscopy had been used to characterize their structure and property. The reset indicated, carbon nanotubes and microtubules protein was linked together closely, and the main properties of microtubules protein was unchanged. Because of the microtubules protein, the dispersion of carbon nanotubes was also improved. The result of UV absorption spectra shows that the successful of the combination between paclitaxel and hybrid material. High-efficiency chromatographic tests show that the content of taxol that the hybrid material with 1 mg can be combined was 0.0012 mg, and carbon nanotubes used as the carrier of taxol became possible.
