In order to realize the hepatocyte-specific targeted delivery of anti-tumor drug and gene, lactosylated chitosan oligosaccharide (LCO) functionalized graphene oxides (GO-LCO) containing quaternary ammonium groups (GO-LCO+) were prepared. The formation and composition of GO-LCO+ were confirmed by FTIR, AFM, TGA and zeta-potential. The in vitro cells uptakes of this functionalized GO were investigated and the results showed that GO-LCO+ can deliver fluorescein FAM-labeled DNA sequence (FAM-DNA) into human hepatic carcinoma cells (QGY-7703) with higher efficiency than positively charged chitosan oligosaccharide (CO) functionalized graphene oxides (GO-CO+) without Lactose acid modification.
