Preparation and properties of reversible hydrogels based on triblock poly(amino acid)s with tunable pH‐responsivity across a broad range

A series of reversible triblock poly(amino acid)s hydrogels with tunable pH-responsivity (pH 3.5–10.0) were synthesized by adjusting the ratio of the blocks. Attributing to the good biodegradability and low cytotoxicity of these triblock poly(amino acid)s, it is obvious that these poly(amino acid)s are potential novel materials in drug delivery and injectable hydrogels.
