<p>A portable biochip scanner that enables multi-channel measurement includes a surface plasmon resonance unit (44) formed in a rotational disk-shape and an optical head (50) projecting light to the surface plasmon resonance unit (44) at an angle within a predetermined range and detecting light totally-reflected from the surface plasmon resonance unit (44). The optical head (50) is movable in a radial direction of the surface plasmon resonance unit (44).
Preferably, the surface plasmon resonance unit (44) comprises a prism disk (42) formed in a ring-shape, and a micro-fluidic disk (43) coupled to a bottom of the prism disk (42). The micro-fluidic disk (42) being provided at a top surface with a plurality of micro-fluidic channels. Preferably, the optical head includes a micro-scanning mirror (52) projecting light from a light source (51) via a reflecting mirror (53) to the surface plasmon resonance unit (44).</p> |
