Abstract
The present invention provides a microneedle, comprising a shaft of a monocrystalline material having at least three walls which are formed by a crystal plane of the monocrystalline material; and a tip connected to an end of the shaft comprising at least three walls which are formed by a crystal plane of the material. The material is preferably silicon. Two of the walls of the tip are formed by the same crystal planes as two walls of the shaft. These two walls are formed by a <111> crystal plane. Preferably, three walls of the tip are formed by a <111> crystal plane.
