Abstract

A pH-responsive synthetic biohybride module poly(L-alanine acrylamide)-block-poly( methylmethacrylate (PAAla-b-PMMA) diblock biohybrids, based on hydrophilic PAAla and hydrophobic PMAA segments, is developed via direct switching from Zinc (Zn) catalyst polymerization. EbiB was used as an initiator to Zn-mediate Reversible Deactivation Radical Polymerization (RDRP) of alanine-derived monomer, Alanine acrylamide (AAla), yielding a series of (PAAla-b-PMAA)-The copolymer's stimuli response has been assessed against pH. The aim of this investigation was to translate this structure into a synthetic polymer. The copolymer is capable of removal of toxic dye from wastewater. This approach not only enhances the effectiveness of dye removal but also contributes to the development of eco-friendly and recyclable materials for water purification applications.
