Abstract: A biosensor structure is provided, which includes a substrate, a center conductor, a first ground conductor, a second ground conductor and a protection layer. The center conductor is disposed on the substrate and defines a detection area at the central area thereof for detection of cells or biomolecules. The first ground conductor is disposed on the substrate and is located opposite to a side of the center conductor. The second ground conductor is disposed on the substrate and is located opposite to another side of the center conductor. The protection layer is disposed on the substrate, the center conductor, the first ground conductor and the second ground conductor. In a thickness direction of the biosensor structure, the protection layer is disposed without substantially overlapping the detection area.

Abstract: Disclosure is a biosensor chip having precise count function comprising: a substrate, a plurality of ground wire waveguide layers, a signal waveguide layer and a protective layer. Wherein, the plurality of ground wire waveguide layers are located on two sides of the substrate, the signal waveguide layer is located on the substrate and between the plurality of ground wire waveguide layers, wherein the signal waveguide layer has a recess which forms a cell sensing region; and the protective layer covers a portion of the ground wire waveguide layers and a portion of the signal waveguide layer to expose the recess.

Abstract: A biosensor chip with nano-structures. The biosensor chip includes a RF biosensor, comprising an isolated substrate; a ground plane; a filtering circuit; at least one cell detection area with nano-structures and a protection layer. The RF biosensor can detect the existence of the cancer cells, high frequency biological effects and the cells relationship between transfers by noninvasive method. The RF biosensor according to the invention can provide high accuracy and sensitivity in cancer cells detection.
