The purpose of this study was to investigate the suitability of phase sensitive smart polymer-based protein formulations in order to deliver a model protein, lysozyme, in a conformationally stable and biologically active form at a controlled rate over extended period of time. Four different formulations, using D,L-poly(lactide) (D,L-PLA) and a solvent mixture of different ratios of benzyl benzoate (BB) and benzyl alcohol (BA), were prepared. Conformational stability and biological activity of lysozyme were studied by differential scanning calorimeter and enzyme activity assay, respectively. We found a significant (P
