Fluorescence detecting device for detecting biomolecule using amorphous-silicon thin film transistor

摘要

The present invention combines the analyte biomolecules in the probe biomolecules attached to a substrate, the present invention relates to a fluorescence detection device for detecting a biomolecule of detecting fluorescence generated by irradiating light on the combined biomolecule. The fluorescence detection device includes a transparent substrate, an optical thin film transistors, capacitors and transfer the thin-film transistor. The transparent substrate, a first region, a second region and a third has an area, the first optical surface is irradiated with the first surface of the second surface and the opposite is to be opposed with the probe biomolecule on the first substrate attachment surface It is arranged. An optical thin-film transistor, thereby generating an electric charge corresponding to the fluorescence originating from the biomolecules bonded is disposed on the second surface of the transparent substrate in the first region. Capacitor, the second side-by-side arrangement with the optical thin-film transistors on the second surface of the transparent substrate in the second region store the electric charges generated from the optical thin-film transistor. And pass thin film transistor, the side-by-side are disposed with the capacitor on the second surface of the transparent substrate in the third region to transfer the charge stored in the capacitor in a separate assay system.
