Abstract

An article having at least one microneedle () is provided. The microneedle includes a base (), an elongated body () having a central axis () and a body diameter (), a tip portion (), a first channel (), and a second channel (). The tip portion includes a tip (), a beveled surface (), and a bevel opening () in the beveled surface. The first channel extends axially from the bevel opening through at least a portion of the elongated body and has a first wall that is substantially aligned with the central axis. The second channel extends radially from the first channel to the bevel opening and has a second wall that is oriented substantially orthogonal to the central axis. The first channel and second channel merge to form the bevel opening.
