Abstract:
An electrode includes a plurality of nanomaterial members that define a plurality of pores. The electrode allows passage of at least 60% of light in the about 390 nm to about 1200 nm wavelength range. The electrode can be used for measuring capacitance, resistance, inductance, electrochemical properties and/or photoelectric properties of an element to be analyzed. A process for fabricating the electrode includes forming on a substrate a conductive pattern comprising a plurality of conductive nanomaterial members and optionally functionalizing a first sub-region of the conductive pattern with a material sensitive to at least a first type of analyte. The conductive pattern can comprise a plurality of pores, and the formed electrode allows passage of at least 60% of light in the about 390 nm to about 1200 nm wavelength range. A detector includes a working electrode, a counter electrode and a reference electrode, each electrode having a plurality of nanomaterials defining a plurality of pores.
