Labeled detection methods


Total Internal Reflectance Fluorescence (TIRF)

Evanescent waves are observed in total internal reflection. Antibodies that are labelled using dye molecules bind to modified surfaces.They get fluorescence-stimulated caused on the evanescent field.



Quantumdots (QDs)

Quantum Dots (QDs) are nanoscopic semiconductor structures. Quantum Dots are smaller than the de-Broglie wavelength of electrons and smaller than the Bohr radius of the exciton. Their size determines the properties of these nanoparticles considerably. The optical characteristics of QDs are of special interest.The properties can be modified by controlling the growth process of the nanoparticles.
