摘要：
An apparatus that includes a nano-projection array and an application unit configured to displace the nano-projection array to thereby deliver a composition (e.g., vaccine) to a controlled depth within the skin. The nano-projection array includes nano-projections carried by a carrier substrate. The application unit includes a peripheral structure and a displaceable carrier. The nano-projection array can be disposed within the peripheral structure. Displacement of the displaceable carrier causes a corresponding displacement to the nano-projection array. The displacement of the displaceable carrier can be controlled. For instance the distance of displacement of the displaceable carrier can be controlled. A method or process for manufacturing the apparatus is also provided.
