Biosensor array formed by junctions of functionalized electrodes

A sensor array, comprising:

• a) a plurality of sensor half elements for measuring a concentration and identifying a plurality of organic target compounds under investigation or related copies thereof within a mixture of organic compounds at least one of said sensor half elements or all of said sensor half elements including an electrical conductor forming a carrier, an electrically insulating layer completely encasing said electrical conductor and a layer of a sensor compound supported on said carrier and said insulating layer;
• b) said layer of sensor compound including a plurality of different sensor compounds wherein each sensor half element contains and/or carries one of said sensor compounds, the sensor compounds binding to a specific binding site of said target compounds, respectively;
• c) wherein each of said sensor compounds is assigned to at least one of said sensor half elements;
• d) wherein each sensor half element intersects or traverses at least one of the other said sensor half elements in a separate junction area;
• e) wherein said sensor compounds of two intersecting or traversing sensor half elements are spaced and/or converge and/or touch each other;
• f) wherein in each junction area an individual sensor is formed with a determined combination of two sensor compounds each said sensor compound being located at one of the intersecting or traversing sensor half elements;
• and
• g) the sensor array having at least two junction areas with different combinations of sensor compounds;
• h) said sensor half elements being aligned in a grid structure, with a plurality of row elements and a plurality of column elements;
• i) said row elements being formed by a number of sensor half elements and said column elements being formed by the remaining said sensor half elements;
• j) said row elements being aligned and spaced next to each other and said column elements being aligned and spaced next to each other;
• k) each said row element intersecting each said column element in at least one said junction area;
• and
• l) each said junction area forming an individual sensor.
