Self-Oscillating Nanogel Particles
Langmuir, 2004Nanogel particles composed of the cross-linked copolymer of N-isopropylacrylamide and ruthenium catalyst for the Belousov−Zhabotinsky (BZ) reaction were prepared by emulsion polymerization. In the aqueous solution containing the BZ substrates, self-oscillation of gel beads on the nanometer scale was achieved.

Nanogels for regenerative medicine
Journal of Controlled Release, 2019Nanogels have been widely explored for drug delivery, but their applications in the tissue engineering field are still quite recent. Regenerative medicine also demands controlled delivery of growth factors and other active substances able to promote cell adhesion and guide cell differentiation and tissue formation.

Here, we synthesized dextrans modified with trivalent cationic or anionic groups. Aqueous solutions of the cationic and anionic dextrans were then mixed resulting in the formation of polyion complex nanogels (PIC-NGs), which have physically crosslinked salt bridges formed between the cationic and anionic groups.

Dual‐Responsive Photocatalytic Polymer Nanogels
Angewandte Chemie, 2019AbstractSelective activation of photocatalysts under constant light conditions has recently been targeted to produce multi‐responsive systems. However, controlled activation, with easy recovery of the photocatalysts, induced by external stimuli remains a major challenge.

Nanogel/Microgel Science and Beyond
Langmuir, 2023Since the first report in 1986, tremendous effort has been devoted to developing a deeper understanding of hydrogel colloidal particles (i.e., nanogels/microgels), including their synthesis, characterization, assembly, computer simulation, and various applications.

Nanogels Capable of Triggered Release
2021This chapter provides an overview of soft and environmentally sensitive polymeric nanosystems, which are widely known as nanogels. These particles keep great promise to the area of drug delivery due to their high biocompatibility with body fluids and tissues, as well as due to their ability to encapsulate and release the loaded drugs in a controlled ...

Magnetic nanogels represent a cutting edge of magnetic soft matter research due to their numerous potential applications. Here, using Langevin dynamics simulations, was analysed the influence of magnetic nanogel concentration and embedded magnetic particle interactions on the self-assembly of magnetic nanogels at zero field.

Molecular Fundamentals of Enzyme Nanogels
The Journal of Physical Chemistry B, 2008The assembly of a monomer around an enzyme as the essential step in the fabrication of enzyme nanogel by in situ polymerization was illustrated by molecular dynamics simulation and evidenced by a fluorescence resonance energy transfer spectrum, using lipase/acrylamide as a model system.
