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
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
Infection associated with implanted biomaterials is common and costly and such infections are extremely resistant to antibiotics and host defenses. Consequently, there is a need to develop surfaces which resist bacterial adhesion and colonization. The broad spectrum synthetic cationic peptide

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
