Using benzoxazine chemistry and bio-based triblock copolymer to prepare functional porous polypeptide capable of efficient dye adsorption

A functional porous PTyr with phenolic OH and amide units through the selective cancelation of the PCL-b-PEO block segment from PCL-b-PEO-b-PTyrBZ triblock copolymer and used for dye adsorption.

Cd2+ coordination: an efficient structuring switch for polypeptide polymers

Stimuli-responsive polypeptides have practical applications in devices and therapeutic delivery. Here we report that coordination to Cd²⁺ metal species can be used as a robust stimulus to control both, α-helix and β-sheet secondary structuring of polypeptide polymers.
