On August 27 - 30, together with Professor Bernhard Wolfrum our PhD students Marta Nikić, Beatrice De Chiara, Sebastian Freko and Hu Peng attended the 4th European BioSensor Symposium in Aachen hosted by University of Applied Sciences, FH Aachen. We enjoyed the enriching tutorial talks by academic experts and the interesting poster sessions by junior researchers very much! Many congrats also to Sebastian for winning the "Best Poster with Short Presentation Award"!
