Micro Scanner Based Fluorescence Measurements on Nano Titer Plates for Environmental Analysis

摘要: There will be a growing need for environmental analyses in liquids in the future. This demands new detection techniques that are faster, less expensive and less harmful to the environment than the present laboratory methods. In a joint venture called LINDAU (" Laser-igduzierte Fluoreszenz-Qetektion auf mikrostrukturierten Probentragern zur Analytik im l_J_mweltbereich") a new system based on the detection of immuno chemically labelled analyts by laser induced fluorescence is being developed. Long term aim is the availability of an automated and miniaturized laboratory that is housed on a single chip.As a first step in this direction the measurements are performed on" nano titer plates “(NTP) with probe volumes in the nanoliter range (similar to the more common micro titer plates with probe volumes in the pi—range that are widely used in analytic laboratories) and the fluorescence excitation is done by a small …
