Determination of the interactions between Zn2+ and water soluble polymer ligands with potential use in controlled drug delivery.


Biodegradable copolymers of aspartic and lactic acids were synthesized for potential use in controlled drug release. The proportion of aspartic acid moieties in the copolymers was 0.9 and 0.1, the molecules were partially branched and had absolute molar masses over 100,000 g/mol. The drug could be attached to the copolymer via metal (particularly zinc) ions… (More)
