D- or L-aspartic acid containing polyacrylamides were synthesized. Binary and ternary complex formation between these polymers with copper and bovine serum albumin was studied by spectroscopic and electrochemical measurement. Depending on the ratio of the polymer/copper and protein/polymer, the mixture exhibited water-soluble and insoluble character. A hypothetical structural scheme for the formation of ternary complexes is proposed. The effect of radiation on these complexes was also investigated.
