Abstract
The present disclosure describes microtips, MicroArrays, MicroArray Patches comprising MicroArrays, delivery devices, and methods of manufacturing and methods of using same. In some embodiments, a substance-loaded MicroArray is prepared by photochemically etching MicroArray outlines in a substrate sheet, the MicroArrays comprising a plurality of microtips, configuring reservoirs in each microtip such as by photochemical half etching, filling each reservoir with a substance to be delivered, and then bending each of the microtips out of planarity such that each microtip comprises a substance-loaded projection disposed an angle relative to the generally planar substrate sheet.

-108. (canceled)
A MicroArray comprising:
- a plurality of microtips formed in a substrate, wherein each microtip of the plurality of microtips comprises a reservoir and a hinge portion, the substrate having a first thickness and each microtip having a second thickness,
- wherein the first thickness of the substrate remains substantially the same as the second thickness of the microtip except where a reservoir exists and where the hinged portion exists,
- wherein each microtip has a proximal end and a distal end, such that the hinge portion is at the proximal end of the microtip where the microtip remains attached to the substrate,
- wherein the hinged portion is thinner than the thickness of the starting substrate.
