In situ crosslinking of a biomimetic peptide-PEG hydrogel via thermally triggered activation of factor XIII.
There is a medical need for robust, biocompatible hydrogels that can be rapidly crosslinked in situ through the use of gentle and non-toxic triggers, which could be used as a surgical adhesive, a bone-inductive material, or for drug and gene delivery. The complete gelation system described here includes calcium-loaded liposomes, hrFactor XIII. thrombin, and an enzymatic substrate based on a fou...
متن کاملIn Situ Mineralization of Magnetite Nanoparticles in Chitosan Hydrogel
Based on chelation effect between iron ions and amino groups of chitosan, in situ mineralization of magnetite nanoparticles in chitosan hydrogel under ambient conditions was proposed. The chelation effect between iron ions and amino groups in CS-Fe complex, which led to that chitosan hydrogel exerted a crucial control on the magnetite mineralization, was proved by X-ray photoelectron spectrum. ...
متن کاملIn situ cell manipulation through enzymatic hydrogel photopatterning.
The physicochemical properties of hydrogels can be manipulated in both space and time through the controlled application of a light beam. However, methods for hydrogel photopatterning either fail to maintain the bioactivity of fragile proteins and are thus limited to short peptides, or have been used in hydrogels that often do not support three-dimensional (3D) cell growth. Here, we show that t...
متن کاملCollagen Crosslinking for Keratoconus
In this issue of JOVR, Derakhshan and co-authors 1 describe the results of crosslinking for patients with early keratoconus. Collagen crosslinking is a recently described technique of corneal tissue strengthening using riboflavin as a photosensitizer and ultraviolet A (UVA) radiation to promote the formation of intra-and interfibrillar covalent bonds by photosensitized oxidation. 2 To date, it ...
