SOLID SUPPORT COATED WITH AT LEAST ONE METAL FILM AND WITH AT LEAST ONE TRANSPARENT CONDUCTIVE OXIDE LAYER FOR DETECTION BY SPR AND/OR BY AN ELECTROCHEMICAL METHOD

摘要

One subject of the present invention is a transparent solid support coated with at least one layer of metal and with at least one layer of transparent conductive oxide (TCO), especially tin-doped indium oxide (ITO) in order to form a solid support that can be used at the same time or independently for detection by SPR and by an electrochemical method. The invention comprises a process for producing such supports, especially by cathode sputtering using a device comprising a radiofrequency (RF) generator, this device also being included in the invention. Another subject of the invention is a kit and a method for detection or identification of an organic or mineral compound by surface plasmon resonance (SPR) and/or electrochemical plasmon resonance comprising or using such supports.
