Corneal collagen cross-linking

open access: yesMiddle East African Journal of Ophthalmology, 2010
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

open access: yesIndian Journal of Ophthalmology, 2013
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]

open access: yesACS Macro Letters, 2014
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.
