Abstract
Provided herein are devices and methods for topically and controllably delivering cargo or collecting samples into or from biological tissues, particularly the skin. These devices permit delivery of cargo and collection of samples from cell layers deep within a tissue. These devices include microstructure arrays comprising nanochannels. Also disclosed is a device comprising a one or more microstructure arrays encased in a frame.
