OBJECTIVE To design a kind of assembled PAMAM dendrimers linked together by using complementary DNA oligonucleotides targeted to cancer cells,and discuss the possiblity and effect of coupled functional PAMAM dendrimers.METHODS G5 PAMAM dendrimers was first partially acetylated and then conjugated with FITC or FA,followed by the covalent attachment of complementary,5-phosphate-modified oligonucleotides.Hybridization of these oligonucleo-bindtide conjugates led to the self-assembly of the FITC and FA-conjugat...
