Description générale

Poly(ethylene glycol) diacrylate (PGEDA) is used for synthesising highly cross-linked hydrogels which are used as biomaterials in tissue engineering. These hydrogels are formed using non-cytotoxic photo initiators. PEG hydrogels can be easily covalently linked to bioactive proteins and peptides which in turn promote specific cell activity either on the surface or within the hydrogel.

Application

This homobifunctional PEG can be used in hydrogel applications; biocompatibilization; thiol-ene coupling; and other applications using cross-linked PEG networks.

Microvascularization of tissue engineered constructs was achieved by utilizing a VEGF-mimicking peptide, QK, covalently bound to a poly(ethylene glycol) hydrogel matrix. The 15-amino acid peptide, developed by D'Andrea et al., was modified with a PEG-succinimidyl ester linker on the N-terminus

We present an easy and effective method for the encapsulation of cells inside PEG-based hydrogel microstructures fabricated using photolithography. High-density arrays of three-dimensional microstructures were created on substrates using this method. Mammalian cells were encapsulated in cylindrical hydrogel microstructures of

Hydrogels with the ability to change shape in response to biochemical stimuli are important for biosensing, smart medicine, drug delivery, and soft robotics. Here, a family of multicomponent DNA polymerization motor gels with different polymer backbones is created, including acrylamide-co-bis-acrylamide
