摘要:
Multiple-layer hydrogels and methods of forming hydrogels having multiple layers are disclosed. The hydrogels are formed of prepolymerization solutions comprising monomers or macromers, particularly polyethylene glycol. The layers are covalently bonded, and the hydrogels may comprise two or more layers.
摘要:
A composite of silica aerogel and a hydrogel synthesized by and a method for the sequential formation thereof including the encapsulation of hydrophobic aerogels with PEG hydrogel via photoinitiated polymerization. The aerogel-hydrogel composite has two layers: the outer layer hydrogel layer is hydrophilic, whereas the inner aerogel core is hydrophobic.

摘要:
Microencapsulation of pancreatic islets within a thin poly(ethylene glycol) (PEG) coat is provided. The PEG coat is functionalized with an insulinotropic agent, glucagon-like peptide 1 (GLP-1). The encapsulated pancreatic islets may be used for the treatment of type I diabetes.
