Abstract
The disclosure provides a drug delivery device that can release a drug or other molecule of interest in response to application of a mechanical force, such as tension, and methods of use thereof. The present disclosure provides a tension-responsive drug delivery device by exploiting a difference in mechanical properties between a drug-loaded core material and a supertiydrophobic barrier coating consisting of interconnected micro- and nano-sized particles formulated via the electrospraying of a mixture of biocompatible polymers.
