This project presents a new modality for cell electro-permeabilisation based on the use of CNTs and external static electric fields to achieve highly drug delivery efficiency. Besides, CNTs are unique materials that absorb infrared (IR) radiation in the special spectral window where body tissues are most transparent. Absorbed IR promotes molecular oscillation leading to efficient heating of the surrounding environment. By using these characteristics of CNTs, we conjugate photosensitizers (PS) on chemically functionalized single-walled carbon nanotubes (f-SWNTs) to combine photodynamic therapy and hyperthermia for killing cancer cells specifically and effectively. Thus, CNT complex drug delivery is promising for improving the efficacy of drug delivery and treatment to decrease side effects for future cancer therapy.奈米碳管電穿孔光動力治療熱治療carbon nanotubeselectro-permeabilisationphotodynamic therapyhyperthermiaEnhanced Cell Electro-Permeabilisation Combined with Phototherapy to Target-Killing Cancer Cells by Using Multi Functional Carbon Nanotubes
