Abstract:
Provided is a small and easy-to-carry light-induced fluorescence measuring device capable of minimizing alignment displacements in an optical system due to impact and so forth, suppressing reflected light and scattered light and so forth from entering a fluorescence measuring unit, and capable of carrying out fast and high-performance measurements. A laser light source (1) for emitting excitation light, a sample case (2), a photomultiplier tube (4) constituting the fluorescence measuring unit, a fluorescence collecting optical system (3) and so forth are embedded in a resin material (6) that is transparent to the excitation light and the light including fluorescence emitted from a sample (S). The resin material (6) is provided in at least part of a light path that guides the fluorescence in the fluorescence collecting optical system (3), and this resin forms a housing that holds the laser light source (1), the fluorescence collecting optical system (3), the photomultiplier (4) and so forth. A pigment having wavelength characteristics for absorbing the excitation light, Raman light generated from the resin, and so forth is contained substantially in a uniform manner in a resin region (61) that surrounds the light path through which the excitation light and the light including the fluorescence pass, so as to absorb all these types of light travelling outside the light path.

Abstract:
The present invention discloses a biosensor for visual detection of an analyte, based on the light to heat conversion properties of metal nanoparticles: the analyte is visually detected by the color change in the support areas (where the analyte is present), produced as a result of the heat generated by the metal nanoparticles where they are irradiated with an external light source. Use of said biosensor in a method for the detection of analytes is also claimed.
