Abstract
A hydrogel system comprising polymer-conjugated albumin molecules is provided for controlled release delivery of therapeutic agents. The polymer is a functionalized synthetic polymer, preferably PEG-diacrylate. The polymer-conjugated albumin is preferably mono-PEGylated albumin. The hydrogel system may comprise a matrix to which the polymer-conjugated albumin molecules are linked via a functional group of the polymer. The matrix may be formed from the same polymer of the polymer-albumin conjugate.
