A cationic star copolymer with a β-cyclodextrin core was developed for nonviral gene transfer to mouse embryonic stem cells (mESCs). The copolymer comprises poly(2-dimethyl aminoethyl methacrylate) as the cationic component and poly(2-hydroxyethyl methacrylate) as the non-toxic stealth component. These materials have very low toxicity and show highly efficient transfection to mESC colonies.

Hydrogels exhibiting selectivity towards lysozyme were produced by metal-ion assisted-imprinting technology. A metal-chelate monomer N-vinyl-2-pyrrolidone is pre-assembled with the template molecule via assistance of Cu(II) ions and co-polymerized 2-hydroxyethyl methacrylate. Lysozyme imprinted hydrogels characterized Fourier transform infrared spectroscopy, swelling tests, scanning electron mi...

Acrylic-type polymeric systems having degradable ester bonds linked to ibuprofen were synthesized and evaluated as materials for drug delivery. Ibuprofen, as a non-steroidal anti-inflammatory drug, was linked to 2-hydroxyethyl methacrylate by activated ester methodology in one-pot procedure. The resulting methacrylic derivative of ibuprofen was copolymerized with 2-hydroxyethyl methacrylate and...

The influence of poly(titanium oxide) obtained using the sol-gel method in 2-hydroxyethyl methacrylate medium on viscoelastic and thermophysical properties interpenetrating polymer networks (IPNs) based cross-linked polyurethane (PU) poly(hydroxyethyl methacrylate) (PHEMA) was studied. It found that both initial organo-inorganic (OI IPNs) have a two-phase structure by methods dynamic mechanical...

Injectable PEG-analogue hydrogels based on poly(oligoethylene glycol methacrylate) have been developed based on complementary hydrazide and aldehyde reactive linear polymer precursors. These hydrogels display the desired biological properties of PEG, form covalent networks in situ following injection, and are easily modulated for improved control over their functionality and physiochemical prop...
