The FLI presented a Zeiss Microscope of the latest generation by means of which the heart beats and blood circulation of zebrafish embryos could be observed. Birgit Perner of the Engert Research Group further explained the importance of fluorescence microscopy to study the development of organs like the kidney. Hundreds and hundreds of interested students and citizens went to the FLI booth to learn about biophotonic methods and to have a look through the eyepieces of the Zeiss microscope.
