Integrated microsystems for controlled drug delivery.

Efficient drug delivery and administration are needed to realize the full potential of molecular therapeutics. Integrated microsystems that incorporate extremely fast sensory and actuation capabilities can fulfill this need for efficient drug delivery tools. Photolithographic technologies borrowed from the semiconductor industry enable mass production of such microsystems. Rapid prototyping allows for the quick development of customized devices that would accommodate for diverse therapeutic requirements. This paper reviews the capabilities of existing microfabrication and their applications in controlled drug delivery microsystems. The next generation of drug delivery systems--fully integrated and self-regulating--would not only improve drug administration, but also revolutionize the health-care industry.
