Hydroxypropyl chitosan (HPCS), a water-soluble chitosan derivate, was modified by introducing photoreactive azide groups (4-azidobenzoic acid, Az-) to the amino groups of HPCS, resulting in a photocrosslinkable Az-HPCS. Novel porous chitosan scaffolds thus were fabricated by ultraviolet (UV) light irradiation

Here, the surface of silicone elastomer was modified with photo-reactive gelatin bearing azidophenyl groups. Two types of gelatin were prepared: one by coupling with azidoaniline and the other by coupling with azidobenzoic acid. The silicone surface was hydrolyzed by oxygen

Grafting of poly (ethylene glycol) (PEG) on the surface of polysulfone (PSF) sheets by simultaneous or sequential UV irradiation with 4-azidobenzoic acid as the photocoupler was carried out. Water contact angle measurements showed that there was a great improvement of

Photo-reactive poly(vinyl alcohol) (PRPVA) was synthesized by introduction of phenyl azido groups into poly(vinyl alcohol) (PVA) and applied for surface modification. PRPVA was grafted onto cell culture plate surface homogeneously or in a micropattern. Human mesenchymal stem cells (hMSCs) cultured

Chitosan (CS) was covalently immobilized onto polylactic acid (PLA) film surface using the photosensitive hetero-bifunctional crosslinking reagent, 4-azidobenzoic acid, which was previously bonded to chitosan by reaction between an acid group of the crosslinking reagent and a free amino group
