Polymer hydrogel nanoparticles and their networks
… responsive hydroxypropyl cellulose (HPC) hydrogel nanoparticles have been synthesized and characterized. The HPC particles were obtained by chemically crosslinking collapsed HPC polymer chains in water-surfactant (dodecyltrimethylammonium bromide) dispersion above the lower critical …

The design of multifunctional hydrogel nanoparticles for drug delivery
Hydrogel micro- and nanoparticles (microgels and nanogels) are a promising class of drug delivery vehicles. Composed of hydrophilic polymers arranged into a cross-linked network structure, nanogels show several attractive features for the delivery of macromolecule therapeutics. For instance, the …

Synthesis and Characterization of Crystalline Assemblies of Functionalized Hydrogel Nanoparticles
Two series monodispersed nanoparticles of hydroxylpropyl cellulose (HPC) and functionalized poly-N-isopropylamide (PNIPAM) particles have been synthesized and used as building blocks for creating three-dimensional networks, with two levels of structural hierarchy. The first level is HPC …

Synthesis of a hydrogel-based vaccine to mimic dendritic cell responses to pathogens
… of microspheres encapsulating chemokines and hydrogel nanoparticles; each nanoparticle contains antigen and DC maturation signals (e.g., TLR ligands). The nanoparticles remain sequestered within the carrier microspheres but the chemokine is released at a controllable rate, creating a local …

pH-sensitive core-shell nanoparticles for intracellular drug delivery
… for the synthesis of monodisperse core-shell hydrogel nanoparticles of 200 nm in diameter. The protonation of tertiary amine groups on the polyDEAEMA core on moving from extracellular to endolysosomal pH resulted in reversible swelling of the nanoparticles with a 2.8-fold diameter change. With …
