DIAGNOSTIC APPARATUS FOR IMMUNOASSAY AND DIAGNOSTIC METHOD FOR IMMUNOASSAY USING THE SAME

摘要

A diagnostic apparatus for immunoassay is provided. The diagnostic apparatus includes a microfluidic chip having fluorescent nanoparticle-biomaterial composites to detect a biological sample, a light source unit providing flat light to the microfluidic chip to generate fluorescence energy caused by a fluorescence resonance energy transfer (FRET) effect between the fluorescent nanoparticle-biomaterial composites, a sensing unit configured to sense the fluorescence energy emitted from the microfluidic chip, a measuring unit configured to convert the fluorescence energy sensed by the sensing unit into a current peak, a display unit configured to convert the current peak into an image, and a power supply unit using a solar low power circuit to supply power required for operations of the light source unit, the sensing unit, the measuring unit, and the display unit. The fluorescent nanoparticle- biomaterial composite is specifically bound to the biological sample to form a fluorescent nanoparticle-bio-conjugated material composite.
