Corneal collagen cross-linking
Corneal collagen cross-linking (CXL) with riboflavin and ultraviolet-A (UVA) is a new technique of corneal tissue strengthening by using riboflavin as a photosensitizer and UVA to increase the formation of intra and interfibrillar covalent bonds by photosensitized oxidation.Keratocyte apoptosis in the anterior segment of the corneal stroma all the way ...

Collagen cross linking: Current perspectives
Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases,

Interfacial Bioorthogonal Cross-Linking [PDF]
Described herein is interfacial bioorthogonal cross-linking, the use of bioorthogonal chemistry to create and pattern biomaterials through diffusion-controlled gelation at the liquid-gel interface. The basis is a rapid (k2 284000 M-1 s-1) reaction between strained trans-cyclooctene (TCO) and tetrazine (Tz) derivatives.

pH-Degradable mannosylated nanogels for dendritic cell targeting [PDF]
We report on the design of glycosylated nanogels via core-cross linking of amphiphilic non-water-soluble block copolymers composed of an acetylated glycosylated block and a pentafluorophenyl (PFP) activated ester block prepared by reversible addition ...

Simple one pot preparation of chemical hydrogels from cellulose dissolved in cold LiOH/urea [PDF]
In this work, non-derivatized cellulose pulp was dissolved in a cold alkali solution (LiOH/urea) and chemically cross-linked with methylenebisacrylamide (MBA) to form a robust hydrogel with superior water absorption properties.
