Abstract

The microneedle for blood extraction and painless injection is a rapidly growing area of interest in bio-applications. Two new types of microneedle array are designed and developed for biomedical application. The one is hollow PMMA microneedle array with very shape tip fabricated by two times X-ray lithography (one time is with X-ray mask and one time is without X-ray mask). The other is PMMA microneedle array with tips and fluid channels fabricated by an X-ray lithography technique. The resist stage of the X-ray system driven by actuators is to realize movement lithography.
