Water-swellable polyelectrolyte microgels polymerized in an inverse microemulsion using a nonionic surfactant

Symmetric and asymmetric adsorption of pH-responsive gold nanoparticles onto microgel particles and dispersion characterisation

“…Microgel particles are found in the food [1], surface coating [2] and cosmetics industry [3], and have the potential to be next generation drug delivery systems [4]. Responsive polymers are of interest because properties such as charge and size can easily be changed, often reversibly, using common environmental triggers such as changes in pH or temperature, which introduces a level of control in their application.…”

Synthesis and characterization of polyion complex micelles and their controlled release of folic acid

“…Both of them are used as hydrophilic and sterically protecting segments in polymeric drug carriers for their well-known characteristics of flexibility, low toxicity, immunogenicity, and antigenicity [17]. 2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPS) is a relatively strong acid [18] and is widely used in personal care products and cosmetic thickeners [19]. Poly(4-vinyl pyridine) (P4VP) and its block copolymer are the major materials for the synthesis of pharmaceuticals.…”

Rheological properties of agar microgel suspensions prepared using water-in-oil emulsions

“…Moreover, microgel suspensions are interesting materials as a rheology control agent [1][2][3][4][5][6][7]. Kaneda et al [8] synthesized a water-swellable microgel in a w/o emulsion system to develop a new type of rheological control agent for cosmetics. Because spherical droplets can be obtained in a liquid-liquid two-phase emulsion, microgel particles that synthesize in the inner phase become spherical.…”
