摘要
Hydrogels have gained general acceptance as biocompatible materials and are the basis of many promising applications in tissue engineering, drug release formulations and biosensors. Polymer processing techniques that can generate miniature hydrogel micro structures are not only critical as scaffolds for tissue re-growth but also very effective for increasing the efficiency of drug delivery and biosensors. Our approach is to use both optical and soft lithographic methods to microfabricate hydrogels. In this paper, we describe a photolithographic process to pattern hydrogel materials and analyze factors influencing sensitivity and lateral resolution. The model system we are investigating is based on 2-hydroxyethyl methacrylate (HEMA), which is well known for its non-toxicity and its widespread use in the contact lens industry.
