- *Abstract
-
An IC-processed microneedle including an interface region and shaft. A shell defines an enclosed channel to form the shaft. The shaft has ports to permit fluid movement therethrough. Microheaters, microdetectors and additional devices may also be fabricated on the microneedle. The small diameter minimizes trauma to the patient yet retains sufficient strength to effectively penetrate biological tissue. The microneedle also permits real-time analysis of a fluid sample.
