Latest Patents

Siddiqui holds a patent for an "Electroanalytical sensor based on nanocrystalline diamond electrodes and microelectrode arrays." This invention features a diamond electrode and a diamond microelectrode array designed for biosensors and electroanalytical applications, such as electrochemical impedance spectroscopy (EIS). The electrode comprises a layer of ultra-smooth conductive nanocrystalline diamond (NCD) with a resistivity of >0.05 Ωcm and a surface roughness of <20 nm R. The diamond layer may include boron or nitrogen-doped ultrananocrystalline diamond (UNCD) with an average grain size of <10 nm and a surface roughness of <10 nm R. The microelectrode array is patterned to define multiple individually addressable electrodes, each with a diameter ranging from 100 nm to 100 μm. The surface of each microelectrode is hydrogen-terminated before bio-functionalization, which involves modifying it with sensing molecules for the detection of specific biological or chemical targets.
