Abstract:
1. A device for delivery of material or stimulus to targets within a body to produce a desired response, the targets being at least one of cells of interest, cell organelles of interest and cell nuclei of interest, the device including a number of projections for penetrating a body surface, and wherein: a) the projections include a targeting section for delivering the material or stimulus to the targets to thereby cause the desired response and a support section for supporting the targeting section; b) the number of projections is selected to deliver material or stimulus to a number of targets that is at least sufficient to produce the desired response, the number of projections being at least 500; c) a spacing between projections is at least partially determined based on an arrangement of the targets within the body, the spacing between at least some of the projections being selected to be greater than a diameter of a target of interest; and d) at least part of at least some of the projections are coated with a non-liquid material.
