Facile Synthesis of Resveratrol Nanogels with Enhanced Fluorescent Emission

“…Chemical synthesis of nanogels can be achieved by direct cross‐linking of polymeric chains or cross‐linking copolymerization . Various polymerization methods were investigated to prepare nanogels or cross‐linked star polymers, such as free radical polymerization, atom transfer radical polymerization (ATRP), reversible addition–fragmentation chain transfer (RAFT), ring‐opening polymerization (ROP), and step‐growth thiol‐ene Michael addition polymerization . During preparations, surfactants or macroinitiators/macromonomers are often needed to control the particle size of nanogels and to avoid macrogelations .…”

“…additional monomers) into the nanogel structure 56,57 or to promote the immiscibility of growing chains during polymerisation. [57][58][59] Evidently, water is chosen as the major solvent and an alcohol (e.g. ethanol, [56][57][58] tert-butanol, 59 or 2propanol [60][61][62] ) is selected as the minor solvent.…”

Synthesis of block cationic polyacrylamide precursors using an aqueous RAFT dispersion polymerization

“…The PAM-based nanogels were obtained via a RAFT dispersion polymerization. 42 Although AM polymers can be synthesized by aqueous RAFT solution polymerization, high viscosities of polymerization systems at high solid contents limits control of the polymerization, and low solid content sacrices polymerization efficiencies. This low-solid issue can be overcome with aqueous RAFT dispersion polymerization to produce CPAMs.…”
