Abstract
Disclosed herein are microneedle devices, kits comprising the microneedle devices, and methods of using the microneedle devices. Specifically, disclosed is a device for transport of a material across a biological barrier of a subject comprising: a plurality of microneedles each having a base end and a tip, with at least one pathway disposed at or between the base end and the tip; a substrate to which the base ends of the microneedles are attached or integrated; and at least one reservoir which is in connection with the base ends of the microneedles array, wherein the reservoir comprises an agent delivery system, wherein the agent delivery system comprises an agent to be transported across the biological barrier, or a means for producing an agent to be transported across the biological barrier, and a means for detecting a physiological signal from the recipient.
