Small interfering RNAs (siRNA) have enabled novel, specific, and efficient treatment of diseases, including cancer. To obtain sufficient well-controlled intracellular delivery, a drug delivery system is essential. Herein for siRNA, composed cationic biodegradable nanogels, presented. P(DEAEMA-co-HEMA-g-PEGMA) nanogels with varying ratios 2-diethyl aminoethyl methacrylate (DEAEMA) 2-Hydroxyethyl...

In this study, thermo-responsive polymeric nanogels were facilely prepared via one-step cross-linking copolymerization of ethylene glycol dimethacrylate/divinylbenzene and ionic liquid (IL)-based monomers, 1,n-dialkyl-3,3'-bis-1-vinyl imidazolium bromides ([CnVIm]Br; n = 6, 8, 12) in selective solvents. The results revealed that stable and blue opalescent biimidazolium (BIm)-based nanogel solut...

A boronate ester crosslinked zwitterionic nanogel (NGCA) with ATP/pH-sensitivity has been developed with an inverse nanoprecipitation technique to achieve a two-stage charge conversion that responds to tumor extracellular conditions (pH 6.5-6.8) and an intracellular acidic environment (pH 5-6). Cationic cytochrome C (CC), a therapeutic protein, has been encapsulated into NGCA through inverse na...

Drug releasing shape memory polymers (SMPs) were prepared from poly(thiourethane) networks that were coated with drug loaded nanogels through a UV initiated, surface mediated crosslinking reaction. Multifunctional thiol and isocyanate monomers were crosslinked through a step-growth mechanism to produce polymers with a homogeneous network structure that exhibited a sharp glass transition with 97...

Medical Implants Biomaterials have diverse physicochemical properties and to apply a functional nanogel-based coating on these different materials, unified approach is ideal which independent of the material composition. In article number 2200141, Patrick Van Rijn co-workers report universal nGel spray strategy that applied metals, ceramics, elastomers, (fluorinated) polymers.
