Influence of free chains on the swelling pressure of PEG-HEMA and dex-HEMA hydrogels
International Journal of Pharmaceutics, 2007Insight in the osmotic behavior of degrading hydrogels is of great importance in the design of biodegradable hydrogels for biomedical applications. This study compares the degradation behavior of PEG-HEMA (hydroxyethylmethacrylated polyethylene glycol) and dex-HEMA (hydroxyethylmethacrylated dextran) hydrogels.

Thermoplastic copolymers of 2-hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) (molar ratio: 75/25 HEMA-MMA) were synthesized using HEMA containing different amounts of ethylene glycol dimethacrylate (EGDMA) to investigate their suitability for cell microencapsulation. Pure HEMA (0.0% EGDMA) was obtained with preparative chromatography to

From HEMA monomers to poly-HEMA systems simulations
2022There is plenty of experimental literature characterizing hydroxyethyl methacrylate (HEMA)-based physical and chemical hydrogels, due to their spread applications in numerous fields, especially in the biomedical one. Transport properties of poly-HEMA hydrogels as well as systems dynamics are of particular interest owing to delivery issues, whether in ...

We report the preparation of stable micelles from random copolymers of 2-hydroxyethyl methacrylate (HEMA) and perfluorophenyl azide (PFPA)-derivatized HEMA (HEMA-PFPA). The copolymers were synthesized by RAFT polymerization at room temperature under mild conditions without affecting the azide functionality.

Methods for Microencapsulation with HEMA-MMA
2003Encapsulation of cells in a membrane prior to implantation holds potential for controlling the adverse immune response that may be generated against the transplanted cells, by physically isolating the cells from the host's immune system. If successful, encapsulation eliminates or minimizes the adverse effects of immunosuppressive therapy and permits ...

Biological clearance of HEMA in guinea pigs
Biomaterials, 2002No toxicokinetic data are available about the dental composite component 2-hydroxyethylmethacrylate (HEMA) in vivo in the literature. Therefore, the excretion of HEMA in feces and urine in vivo and, using the pendular perfusion technique with segments of jejunum and colon, in the biliary and enteric excretion in situ were investigated in anesthetized ...
