Abstract
A core-shell microneedle system and a method of manufacturing the microneedle system provides a pulsatile drug delivery system which is programmed to release drugs/vaccines at predictable times using biodegradable polymers and with controllable dosages. This microneedle system can be fully embedded into the skin and then release drugs/vaccines as sharp bursts in a timely manner, similar to multiple bolus injections.
