BACKGROUND The ability to present signalling molecules within a low fouling 3D environment that mimics the extracellular matrix is an important goal for a range of biomedical applications, both in vitro and in vivo. Cell responses can be triggered by non-specific protein interactions occurring on the surface of a biomaterial, which is an undesirable process when studying specific receptor-ligan...

A novel nano-initiator containing kojic acid moiety, [5-(benzyloxy)-4-oxo-4H-pyran-2-yl)methyl-2-bromo-2-methylpropanoate was synthesized by the reaction of 5-(benzyloxy)-2-(hydroxymethyl)-4H-pyran-4-one with 2-bromoisobutyryl bromide in triethylamine and used as initiator in the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate in the presence of Cu(0)/CuCl2and N,N...

When cellulose nanocrystals (CNCs) are isolated from microfibrils, the parallel arrangement of chains in crystalline domains is retained so that all reducing end-groups (REGs) point to one crystallite end. This permits selective chemical modification end CNCs. In this study, two reaction pathways compared selectively attach atom-transfer radical polymerization (ATRP) initiators REGs CNCs, using...

In recent years, there has been a growing interest in the formation of copolymer-lipid hybrid self-assemblies, which allow combining and improving main features pure lipid-based copolymer-based systems known for their potential applications biomedical field. As most common method used to obtain giant vesicles is electroformation, so far low Tg polymers flexibility at room temperature. Copolymer...

Abstract Alkyl bromides are used as initiators in most of the atom transfer radical polymerization (ATRP) process and play an important role for controlling ATRP equilibrium. In this work, effect solvent on equilibrium constant ( K ) rate activation k act three isomeric alkyl [namely, N -phenyl(3-bromo-3-methyl)succinimide, -phenyl(3-bromo-4-methyl)succinimide, -phenyl(3-bromomethyl)succinimide...

Abstract Synthetic routes for functionalization of cellulose membranes by polymer chains characterized controlled structures are constantly developed to precisely adjust the properties prepared material while minimizing impact on membrane performance. The review presents a critical and integrative evaluation prior research atom transfer radical polymerization (ATRP) techniques, emphasizing meth...

Abstract Surface molecularly imprinted cellulose‐synthetic hybrid particles are prepared via atom transfer radical polymerization (ATRP). The two‐step process involves the immobilization of α‐bromoisobutyryl bromide in pristine microcrystalline cellulose, to generate ATRP macroinitiator particles, and then creation a crosslinked‐imprinted shell surface considering 4‐vinylpyridine (4VP) ethylene...
