  • Microneedles and microneedle fabrication
    Publication number: 20060202385
    Abstract: A master mould is made by wire cutting a plate in two or more directions to provide a base with an array of master mould needles protruding therefrom. The size and shape of the master mould needles can readily be varied by varying the angles of upward and downward cuts in the two or more directions. The master mould is used to make a secondary mould by hot embossing a secondary mould plate onto the master mould. This forms through-holes in the secondary mould. The secondary mould is plated with a layer of metal, which forms a microneedle array.
