A microprojection array having at least first (62) and second (64) microprojections, the first and second microprojections having inner (67a, b) and outer (65a, b) faces, the first microprojection inner face being disposed substantially parallel to the second microprojection inner face; and a biocompatible coating disposed on the first and second microprojection inner faces, the first and second microprojections being adapted to substantially restrict contact of the coating with biological tissue during insertion of the first and second microprojections into the tissue.
