Abstract. Five types of carbon nanotube (CNT) scaffolds were prepared by vacuum filtration of the dispersed single-wall carbon nanotubes (SWCNTs), acid-treated SWCNTs, multi-wall carbon nanotubes (MWCNTs), acid-treated MWCNTs, and amylose-wrapped SWCNTs in water onto porous poly(vinylidene chloride) membranes. The influence of these scaffolds on human cervical carcinoma HeLa cells was inve…
