Functionalized carbon nanomaterials as nanocarriers for loading and delivery of a poorly water-soluble anticancer drug: a comparative study

Carbon nanomaterials such as multiwalled carbon nanotubes (MWCNTs) and graphene oxide (GO) have been functionalized by highly hydrophilic and biocompatible poly(vinyl alcohol) (PVA) for loading and delivery of an anticancer drug, camptothecin (CPT). For the first time, CPT was loaded onto MWCNT-PVA and GO-PVA through pi-pi interactions and its capability to kill human breast and skin cancer cells was investigated.
