Nanogels and microgels are soft, deformable, and penetrable objects with an internal gel-like structure that is swollen by the dispersing solvent. Their softness and the potential to respond to external stimuli like temperature, pressure, pH, ionic s

The tunable swelling and rolling of films assembled via layer-by-layer (LbL) methods from poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm-co-AAc) microgels and poly(ethylenimine) (PEI) have been systematically studied. Microgel/PEI films assemble

Multilayer coatings made from hydrogel microparticles (microgels) are conceptually very simple materials: thin films composed of microgel building blocks held together by polyelectrolyte "glue". However, the apparent simplicity of their fabrication a

Poly(N-isopropylacrylamide)(pNIPAm) microgels were synthesized by precipitation polymerization at temperatures ranging from 37 °C to 45 °C using the redox initiator system ammonium persulfate (APS)/N,N,N’,N’-tetramethylethylenediamine (TEMED),

We describe the assembly of two-component, hydrogel microparticle (microgel) monolayer films onto solid substrates via passive Coulombic adsorption from solution. By using two different microgel types with nearly identical sizes but different degrees

Thermoresponsive poly(N-isopropyl acrylamide) (pNIPAm) microgels possessing a hollow structure have been synthesized from core-shell nanoparticles upon oxidation of the particle core, followed by removal of the produced polymer segments by centrifuga

We report investigations on the swelling behavior of poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm-co-AAc) microgel thin films as a function of pH using quartz crystal impedance (QCI) analysis and surface plasmon resonance (SPR) spectroscopy. I

Hybrid thermoresponsive core–shell nanoparticles composed of a non-responsive poly(butyl methacrylate) (pBMA) core and a thermoresponsive poly(N-isopropylacrylamide) (pNIPAm) shell have been synthesized by two-stage free radical polymerization. A p

We report investigations of the assembly of thermoresponsive, 4-acrylamidofluorescein-modified (indicated by an asterisk) poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm-co-AAc*) microgel thin films via a traditional alternate layer deposition pr

We report on the deswelling behavior of microcomposite hydrogel films composed of poly(N-isopropylacrylamide) (pNIPAm). These films were synthesized first by formation of pNIPAm microgel particles via precipitation polymerization, followed by polymer
