General description

Poly(ethylene glycol)-block-Poly(2-(Dimethylamino)ethyl methacrylate) quaternized (PEG-b-PQDMAEMA) is a biocompatible block polyelectrolyte composed of a neutral PEG block and a cationic quaternized Poly(2-(Dimethylamino)ethyl methacrylate) (PDMAEMA) block. The PQDMAEMA carries quaternary ammonium salt moieties along the polymer chain.

application

  • Antimicrobial applications
  • Non-viral gene delivery

    PEG-b-PQDMAEMA is a versatile polymer with applications in antimicrobial applications and gene delivery. Due to its high efficacy in antimicrobial systems, it is an ideal candidate for the fabrication of long-lasting, contact-active bactericidal materials. PQDMAEMA is also a promising material for non-viral gene delivery. PEGylation of PQDMAEMA reduces cytotoxicity and increases gene delivery efficiency.
