We investigate the gel formation from the equilibrium sol phase in a simple model that has the characteristics of (colloidal) gel-forming systems at a finite temperature. At low volume fraction and low temperatures, particles are linked by long-living bonds and form an open percolating network. By means of molecular dynamics simulations, we study the lifetime of bonds and nodes of the gel netwo...

Tissue loss or organ failure caused by injury or damage is one of the most serious and costly problems in human health care. Tissue engineering, proposed by Langer et al. in the early 1990’s (Langer & Vacanti, 1993), is an emerging strategy of regenerative biomedicine that holds promise for the restoration of defect tissues and organs. The concept of tissue engineering is defined as “the applic...

PURPOSE An in situ forming hydrogel was evaluated as a potential vitreous substitute in rabbits. METHODS The hydrogel used a disulfide cross-linker that was then reduced to produce an injectable thiol-containing polymer solution. The disulfide cross-links reformed by air oxidation of the thiols and produced a stable hydrogel once inside the eye. The polymer was clear, autoclavable, and could ...

Article history: Received on: 29/05/2014 Revised on: 12/06/2014 Accepted on: 30/06/2014 Available online: 28/07/2014 In this study effect of gamma irradiation sterilization and storage conditions on thermal properties of phase sensitive granisetron in situ forming implant (ISFI) was investigated. ISFI was prepared by mixing Poly (DLlactide-co-glycolide) (PLGA) with dimethylsulfoxide (DMSO) : pr...

Novel BODIPY forming triplet excited states via the SOCT-ISC process was used for polymerization of methacrylate monomers inside a hybrid sol–gel material. Holographic recording diffractive structures with high efficiency demonstrated.

Tripeptide with redox active chemical entities based smart organogels have been used for in situ formation and stabilization of gold and silver nanoparticles within the supramolecular gel networks and the gold nanoparticles are aligned in arrays along the gel nanofibers of peptide 1-toluene gels.
