Evaluation of amino acid detachment and cytotoxicity of polymers. Remaining amines in the block copolymers after incubation in pH 7.4 10 mM PBS (a) and pH 5.0 10 mM sodium acetate (b) at 37°C determined by fluorometric assay with fluorescamine. Data are presented as the average ± S.D. (n = 3). (c) Cytotoxicity of polymers against HEK293 cells. The cells were incubated with the polymers for 24 h. Data are presented as the average ± standard deviation (n = 3).
