Abstract

A microneedle device (200) including at least one microneedle (1) having one or more nanowires (203) on a surface of said at least one microneedle. The microneedle device is typically used in a sensor such as a sensor for monitoring glucose levels in the body and the nanowires may have a membrane (207) covering at least part of the nanowires.

Claims

1. A microneedle device for use in a sensor, said microneedle device including at least one microneedle having one or more nanowires on a surface of said at least one microneedle.
