Dna branched polymer
WebThe polyplexes which are formed between cationic polymers and DNA through electrostatic interactions and thus known as polycation/DNA complexes, are by far the most widely used non-viral gene delivery vectors. Many factors such as molecular weight, surface charge, charge density, hydrophilicity and the structure of cationic polymers affect gene ...
