Sequence-Controlled Polymerization-Induced Self-Assembly

ACS Macro Letters, 2019
We herein present sequence-controlled polymerization-induced self-assembly (PISA) via photoswitchable reversible addition-fragmentation chain transfer (RAFT) copolymerization of oppositely-charged monomers using polyethylene glycol chain transfer agent in water at 25 °C.

Polymerization-Induced Self-Assembly Promoted by Liquid–Liquid Phase Separation

ACS Macro Letters, 2019
Polymerization-induced self-assembly (PISA) is a powerful method for the synthesis of polymeric kinetically frozen core nanoparticles. However, the PISA synthesis of biologically important polymeric fluidic materials is unexplored. Herein we present a liquid-liquid phase separation mode PISA.

Polymerization-Induced Self-Assembly of Micelles Observed by Liquid Cell Transmission Electron Microscopy

ACS Central Science, 2018
In this paper, we describe the use of liquid cell transmission electron microscopy (LCTEM) for inducing and imaging the formation of spherical micelles from amphiphilic block copolymers. Within the irradiated region of the liquid cell, diblock copolymers

Simultaneous Polymerization‐Induced Self‐Assembly (PISA) and Guest Molecule Encapsulation

Macromolecular Rapid Communications, 2013
Nanoparticles with various morphologies such as micelles, worm‐like/rod‐like and spherical vesicles are made using a polymerization‐induced self‐assembly (PISA) approach via a one‐pot RAFT dispersion polymerization. On polymerization/self‐assembly, we report a concurrent highly efficient loading of guest molecules within the nanoparticle structures ...

Synthesis of Multifunctional Polymersomes Prepared by Polymerization-Induced Self-Assembly. [PDF]

Polymers (Basel), 2023
Polymersomes are an exciting modality for drug delivery due to their structural similarity to biological cells and their ability to encapsulate both hydrophilic and hydrophobic drugs. In this regard, the current work aimed to develop multifunctional polymersomes, integrating dye (with hydrophobic Nile red and hydrophilic sulfo-cyanine5-NHS ester as ...

Polymerization-Induced Self-Assembly of Nonlinear Polymers. [PDF]

Chemistry
ABSTRACT Polymerization‐induced self‐assembly (PISA) has become a scalable route to block copolymer nanoparticles with tunable morphologies, but most established PISA formulations focus on linear architectures. This review surveys recent progress in extending PISA to nonlinear polymers—highlighting how polymer topology reshapes ...
