Abstract: A method of preparing a functionalized electrode array is provided. The method includes depositing a conductive material onto the surface of a substrate by droplet-based printing of particles comprising an electrically-conductive material. The surface of the conductive material is functionalized with a binding reagent that binds to an analyte. A three-dimensional electrode array and microfluidic test device are also provided.

Abstract: A multiplexing electrochemical point-of-care biosensing device that provides picomolar level accuracy and high selectivity and which requires only seconds to provide the response. The biosensing device is capable of being mass manufactured due to a molding process used to fabricate the working electrode of the device, which consists of an array of micropillars coated with a biosensitive material.
