Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...
