Cationic polymers are one of the major nonviral gene delivery vectors investigated in the past decade. In this study, we synthesized several cationic copolymers using atom transfer radical polymerization (ATRP) for gene delivery vectors: pluronic F127-poly(dimethylaminoethyl methacrylate) (PF127-pDMAEMA), pluronic F127-poly

Mikrochimica acta, 185(8), 370-370 (2018-07-11)
Poly(2-naphthyl acrylate) was first grafted onto silica-coated magnetic nanoparticles by surface-initiated atom transfer radical polymerization to prepare a reversed-phase magnetic adsorbent. The resulting polymer brush displays enhanced extraction efficiency by offering active sites on the surfaces of adsorbent. It was

Journal of separation science, 40(3), 779-788 (2016-11-22)
Many bioanalytical methods rely on electrophoretic separation of structurally labile and surface active biomolecules such as proteins and peptides. Often poor separation efficiency is due to surface adsorption processes leading to protein denaturation and surface fouling in the separation channel.
Sun Hwa Lee et al.
Macromolecular rapid communications, 31(3), 281-288 (2010-02-02)
A method for growing polymers directly from the surface of graphene oxide is demonstrated. The technique involves the covalent attachment of an initiator followed by the polymerization of styrene, methyl methacrylate, or butyl acrylate using atom transfer radical polymerization (ATRP).

The Journal of organic chemistry, 72(15), 5923-5926 (2007-07-03)
Reaction of 2-substituted dienamides with catalytic amounts of copper halide/tripyridylamine (TPA) furnishes either 5-exo or 6-endo products with the outcome dependent upon the radical initiating unit. Reaction of 3-substituted dienamides produces beta-lactams via a 4-exo cyclization with termination of the

Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands

We presents an article about Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands, and the emergence of living radical polymerization mediated by transition metal catalysts in 1995, which was a seminal piece of work in the field of synthetic polymer chemistry.

ARGET ATRP: Procedure for PMMA Polymer Brush Growth

We presents an article about ARGET ATRP, and its procedure for PMMA polymer brush growth. Surface preparation before polymer brush growth consists of two steps: surface cleaning and initiator monolayer deposition.

Typical Procedures for Polymerizing via ATRP

An article about the typical procedures for polymerizing via ATRP, which demonstrates that in the following two procedures describe two ATRP polymerization reactions as performed by Prof. Dave Hadddleton′s research group at the University of Warwick.
