Abstract:
A surface plasmon resonance (SPR) measurement assembly, comprising:a waveguide array comprising a plurality of planar waveguides into which light is guided via a light entrance side and a light exit side in at least one dimension, and each of which comprises at least two parallel interfaces, the center-spacing of said individual waveguides corresponding to a one or two-dimensional regular matrix and each and every waveguide is provided with a SPR-compatible sensor area; a light source; a wavelength-selective assembly and an optical system downstream of said light source, said optical system being configured so that said light entrance sides of said waveguides of said waveguide array are illuminated in parallel, said wavelength-selective assembly being configured to set the wavelength of said light to a predefined light wavelength; an imaging optical system and a CCD chip configured so that said light emerging from each and every waveguide is detected by a cluster of CCD pixels of said CCD chip in each case; and a computer including image processing software configured so that a light intensity value of said light emerging from each and every waveguides is computed and following data storage of said intensity value, set wavelength and coordinates of said waveguide array said wavelength-selective assembly is set to a further light wavelength via a control line for the purpose of imaging an intensity spectrum.
