Abstract: The object of the present invention is a device (1) for the transdermal delivery of active molecules. The device (1) comprises a support element (8) and a plurality of micro-needles (10) that protrude from a first surface of the support element (8), the support element (8) and the micro-needles (10) being both permeable to the active molecules. The device (1) further comprises a porous membrane (7) configured to be loaded with said active molecules, which lies on a second surface of the support element (8). Characteristically, the porous membrane (7) is configured to behave, from an optical viewpoint, as a Bragg mirror. Further objects of the present invention are the following uses of the device (1): for monitoring the release and/or the decay of the active molecules, for the optical control of the release of the active molecules and for the thermal control of the release of the active molecules.

Abstract: The present invention relates to a micro-needle (7; 8; 9) for the transdermal administration of active molecules and/or for the sampling of biological fluids. The micro-needle (7; 8; 9) is made of polymeric material through photolithography. A cavity is defined in the micro-needle (7; 8; 9). The present invention further relates to a method for obtaining through photolithography at least one micro-needle (7; 8; 9) for the transdermal administration of active molecules and/or for the sampling of biological fluids. A photo-cross linking polymer is exposed in liquid phase to an energy radiation causing the hardening thereof. A photolithographic mask (1; 2) is interposed between the source of the energy radiation and the photo-cross linking polymer. The photolithographic mask (1; 2) is configured in a manner such to generate in the photo-cross linking polymer a peripheral shadow area, a central shadow area and a lighting area confined between the peripheral shadow area and the central shadow area.

Abstract: A microneedle array device includes a substrate and an array of microneedles on the substrate. Each microneedle includes a redox enzyme and redox mediator and an electrically conductive layer on the substrate. The electrically conductive layer may extend partway up each microneedle exposing the tip thereof.
