摘要：
This invention provides methods and processes to attach or bond hydrogels to suitable surfaces using irradiation techniques and also provides methods and processes to create crosslinked regions in hydrogel articles using these irradiation techniques. Specifically, lasers at wavelengths tuned to the irradiation absorption bands of hydroxyl groups, carboxylic acid groups or water may be used to attach or bond hydrogels to surfaces such as soft tissue and hydrogel surfaces or to crosslink regions in hydrogel articles.
