Abstract: The present invention relates to a nanowire array (15, 16) for electrically-controlled elution of a therapeutic composition (5) comprising a plurality of nanoscopic-sized wires (12, 12), nanowires, attached to an electrically conducting solid support (7), said nanowires formed from electroactive conjugated polymer (4) containing or doped with said therapeutic composition (5) coated over a plurality of nanoscopic sized electrically conducting protrusions (8). It also relates to a method for preparing a nanowire array and an electrode.

Abstract: The invention concerns a method which consists in first subjecting the polyimide sheet to ionic bombardment, followed by an irradiation in the visible domain and finally a relatively brief chemical etching. Said method enables a thin polyimide sheet comprising pores, of nanometric to micrometric size, having a substantially cylindrical shape and substantially equal diameters to be obtained.

Abstract: The invention relates to a method of creating pores in a polymer material in sheet form or a polymer layer such as a thin film with a thickness equal to around 100 nanometers, previously deposited on a metallic base. The invention further relates to a method of creating pores in a polymer material in sheet form, such as polycarbonate or any other equivalent material, the said method making it possible to obtain porous areas with controllable sizes and shapes, these areas being distributed according to densities and locations which can also be controlled.

Abstract: The invention relates to a method for creating pores in a sheet polymer material. The invention more particularly relates to a method for creating nanoscale pores, typically of the order of less than 200 nm, in a polymer material such as sheet polycarbonate or any other equivalent material.
