Measurement of chemical and/or biological samples, useful for screening interactions between two bio-molecules, comprises excitement of a marker with electromagnetic radiation of one wavelength or polarization from a pulsed transmitter

摘要

To measure chemical and/or biological samples, using spectroscopy or microscopy and especially with luminescent spectroscopy, comprises at least one sample with a marker in a measurement volume which is exposed to electromagnetic radiation to excite the marker with at least two different wavelength ranges and/or polarizations. The marker transmits emission wavelength ranges which are detected. An Independent claim is included for an apparatus to measure chemical and/or biological samples and especially by luminescent spectroscopy, with a pulsed transmitter (12) to give electromagnetic pulses in at least one wavelength range and/or polarization.
