pH-Responsive Schizophrenic Diblock Copolymers Prepared by Polymerization-Induced Self-Assembly [PDF]

Macromolecules, 2017
Polymerization-induced self-assembly (PISA) is used for the highly convenient and efficient preparation of ampholytic diblock copolymer nanoparticles directly in acidic aqueous solution. Cationic nanoparticles comprising a protonated polyamine stabilizer block and a hydrophobic polyacid core-forming block are formed at pH 2. Micelle inversion occurs at

Self-Assembling Peptide—Polymer Nano-Objects via Polymerization-Induced Self-Assembly [PDF]

Macromolecules, 2020
Self-assembling peptides (SAPs) have been extensively studied for their ability to form nanoscale ordered structures driven by noncovalent molecular interactions. Meanwhile, polymerization-induced self-assembly (PISA) has been exploited as a facile and efficient way to produce various amphiphilic block copolymer nano-objects, whose self-assembly was ...
