Post-functionalization of drug-loaded nanoparticles prepared by polymerization-induced self-assembly (PISA) with mitochondria targeting ligands

Beilstein Journal of Organic Chemistry, 2021
Herein, the postfunctionalization of different non-fouling PISA particles, prepared from either poly(oligo ethylene glycol methyl ether methacrylate) (pPEGMA) and the anticancer drug PENAO (4-(N-(S-penicillaminylacetyl)amino)phenylarsenonous acid) or ...

Toward Sulfur-Free RAFT Polymerization Induced Self-Assembly [PDF]

ACS Macro Letters, 2017
Polymerization induced self-assembly (PISA) using methacrylate-based macromonomers as RAFT agents is an unexplored, attractive route to make self-assembled colloidal objects. The use of this class of RAFT-agents in heterogeneous polymerizations is however not trivial, because of their inherent low reactivity.

Ring-opening polymerization-induced crystallization-driven self-assembly of poly-L-lactide-block-polyethylene glycol block copolymers (ROPI-CDSA)

Nature Communications, 2020
A key challenge in the self-assembly of block copolymers is obtaining independent control over molecular structure and hierarchical structure in all dimensions using scalable one-pot chemistry.

High‐performance nano‐splitters containing aggregation‐induced emission luminogens for stereoselective crystallization obtained via polymerization‐induced self‐assembly

Aggregate, 2021
Collecting both enantiomorphs with high optical purity and yield in a single crystallization process can be achieved by adding aggregated polymeric “tailor‐made” additives, known as nano‐splitters.

Systematic analysis of nucleation-dependent polymerization reveals new insights into the mechanism of amyloid self-assembly [PDF]

, 2008
Self-assembly of misfolded proteins into ordered fibrillar aggregates known as amyloid results in numerous human diseases. Despite an increasing number of proteins and peptide fragments being recognised as amyloidogenic, how these amyloid aggregates ...

A Critical Appraisal of RAFT-Mediated Polymerization-Induced Self-Assembly [PDF]

Macromolecules, 2016
Recently, polymerization-induced self-assembly (PISA) has become widely recognized as a robust and efficient route to produce block copolymer nanoparticles of controlled size, morphology, and surface chemistry. Several reviews of this field have been published since 2012, but a substantial number of new papers have been published in the last three ...
