Abstract: A high-speed device, for inspecting a large area of an object, which includes: a terahertz wave generation portion configured to generate a terahertz wave; a ring beam forming portion configured to form a ring beam by using the terahertz wave incident from the terahertz wave generation portion; a rotary mirror configured to reflect the ring beam formed by the ring beam forming portion while rotating to allow the ring beam to be incident on an inspection target object; and a detector configured to detect a ring beam generated from the inspection target object.

Abstract: There is provided a paper-based colorimetric sensor kit for quickly and simply diagnosing mercury in situ with a naked eye. The paper-based colorimetric sensor kit includes: a circular template for rolling circle amplification (RCA); a primer that does not hybridize to the circular template when a mercury ion is bonded to a primer that hybridizes to the circular template; a DNA polymerase; a sensing material kit including a nanoparticle probe labeled to a DNA coil formed in the circular template for RCA; and a radial chromatography paper.
