Welcome to the 2nd Sino-German SymposiumWe are very pleased to welcome you to the 2nd Sino-German Symposium on Singletoxygen and photodynamic effects.About 27 scientists from PR China, 22 from Germany, one special speaker from USA,one from Ireland and two from Brazil will report about their latest results in singletoxygen research.The symposium is dedicated to different aspects of singlet oxygen research, startingwith fundamental questions of photosensitized generation and direct detection ofsinglet oxygen. We devote particular attention to the question of 2nd and 3rd generationphotosensitizers for clinical use. This time, amongst clinical aspects, two sessions arededicated to the photodynamic inhibition of microorganisms. The exciting topic ofusing singlet oxygen luminescence as a tool for optimization of photodynamic treatment in situ will be discussed on the symposium, too.We would like to thank all of the participants – including our excellent students – fortheir substantial contribution towards making the symposium successful.We hope that by experiencing the open atmosphere of this meeting you will get newinsights and learn more about the fascinating new prospects of using the photodynamic effect. This 2nd symposium should give all of us new impulses, inspirations andthe basis for new scientific and social contacts to create and develop new networks.We will spare no effort to make the symposium informative and inspiring for you andhope, that you will have an enjoyable week in Berlin.Prof. Beate RöderGerman ChairHumboldt-Universität zu BerlinProf. Buhong LiChinese ChairFujian Normal University

She is leading the photobiophysics group and supervised about 20 PhD students. She received her PhD degree inExperimental Physics from HU Berlin in 1982 and the habilitation in 1986. Her research focuses on molecular photobiophysics, especially on fundamental research inthe field of photosensitization and artificial photosynthesis. Beside these topics herresearch was and is focused on the development of time-resolved optical methodsfor detection of very low light intensities. She works more than 30 years on directspectroscopic detection of singlet molecular oxygen, the last years in particular ontime-resolved luminescence detection. In 1986 she was awarded with the HumboldtResearch Price for her habilitation in the field of fundamental research on mechanisms in PDT. 1989 she was a visiting scientist at Bowling Green State University (USA)in the group of Michael Rodgers, one of the pioneers in singlet oxygen luminescence detection. In the 90is she also visited the Weizmann Institute in Israel (Prof. A.Scherz, Prof. Y. Salomon), In 2009 she was awarded with a Walton Professorship byScience Foundation Ireland.Volkhard May is Privatdozent for Theoretical Physics at the Department of Physics,Humboldt-Universität zu Berlin since 1997. He is the head of a group focusing on thetheory of charge and energy transport in molecular systems. About 15 PhD studentshave been supervised by him. His PhD degree in Theoretical Physics received fromthe Humboldt-Universität zu Berlin in 1981, and he got the habilitation in 1987 fromthe College of Education at Güstrow. His research focuses on Theoretical ChemicalPhysics, especially on photoinduced kinetic phenomena in nanosystems formed bymolecules, semiconductor nano-crystals and metal nano-particles. His actual interestis on different mechanisms to achieve an enhancement of singlet oxygen luminescence. In 1981 he was awarded by the Humboldt Price for his PhD thesis.Steffen Hackbarth received his Ph.D. degree in experimental physics from HU Berlinin 2000. Ever since, he was working in the field of time-resolved spectroscopy in thetime range ps to ms with a special focus at the triplet processes of photosensitizers.He is member of the photobiophysics group and scientist in charge for the singletoxygen lab and especially the highly sensitive singlet oxygen detection. He co-supervised one Ph.D. and several Master/ Diploma students. Since 2011 he is leader of theadvanced practical courses for the physics students at HU-Berlin. His research focuses on molecular photobiophysics, especially on fundamental research in the fieldof photosensitization and energy transfer processes in multi-chromophoric systemsdesigned for Photodynamic therapy as well as singlet oxygen luminescence detec-8

Sinceher diploma in Biophysics 2007 she is working in this group in the field of in vitroexperiments for Photodynamic Therapy. She received her PhD degree in 2011 for invitro investigation of biodegradable nanoparticles as drug carrier for the Photodynamic Therapy. The PhD thesis was part of the German-Chinese joint research project“NanoCancer” funded by the German Federal Ministry of Education and Research.During her PhD she spend 6 month in the Group of Mathias O. Senge in the Instituteof Molecular Medicine at the Trinity College Dublin, Ireland. 2010 she chose a newfocus for her research: The Photodynamic inactivation of microorganisms. Startingwith the Photodynamic inactivation of bacteria (PIB) the interest spread to variousmicroorganisms relevant in medical and environmental research. A special focus isthe investigation of Photodynamic inactivation of mold fungi and their conidia.Wolfgang Bäumler is professor for experimental dermatology at the Department ofDermatology, University Hospital of Regensburg in Germany since 2008. He studiedphysics at the University of Regensburg and graduated with a diploma 1987. Thetopic of his PhD thesis was spectroscopy of dye molecules using femtosecond lasers.After his PhD thesis he moved to the medical faculty in 1992 and is working in different fields of laser medicine and photodynamic therapy to date. He gained muchexpertise in detecting singlet oxygen by its very weak luminescence signal. Singletoxygen is a major species to kill tumor cells or pathogenic microorganisms. He iscollaborating with scientific partners in Germany, European countries and the United States. At present he focussed on the development of a sustainable antimicrobialphotodynamic therapy that kills pathogenic and multiresistant bacteria using naturalphotosensitizers.Tim Maisch studied Biology at the Univ. of Erlangen-Nuremberg, Germany. In 1997he received his diploma and achieved his Ph.D. with a thesis titled „Upregulationof protein expression on endothelial cells infected with human cytomegalovirus” in2001. Since 2002, he has been working as postdoctoral fellow at the Dept. of Dermatology, University Hospital of Regensburg on photodynamic inactivation of multi-resistant bacteria. Main objectives are to investigate the role of singlet oxygen andoxygen consumption in photodynamic inactivation of bacteria as well as the detectionof singlet oxygen directly by its luminescence. One focus is the development of newphotosensitizers for the photodynamic treatment of bacterial and fungal infections.9

Chinesisch-DeutschesZentrum fürWissenschaftsförderung中德科学中心A second focus in cooperation with the Max-Planck-Institute for Extraterrestic Physics (MPE) is the application of cold atmospheric plasma against microorganisms.He gained his Postdoctoral Habilitation in 2009 (venia legendi). He is a member ofthe American Society for Microbiology. Since 2006, he achieved several Awards tosupport the research interest in antimicrobial photodynamic therapy (e.g. “PDT-2006Award”to support the research interest in photodynamic therapy and fluorescencediagnosis of skin diseases and “9th Arnold-Rikli-Award” to support photo-biologicalresearch interests of light in relation to human medicine in the future).Hans-Peter Berlien graduatied from the faculty of medicine at the Freie UniversitätBerlin in 1976 and became medical assistant at the University Clinic Berlin Steglitzwhere he certified as a physician, started his surgical education and received his doctorate specializing in paediatric surgery in 1981. Since 1985 he is medical director ofthe Centre for Laser and Medical Technology Berlin (LMTB). After his postdoctorallecturing qualification he became professor for laser medicine at the Freie UniversitätBerlin in 1989. From 1996 to 2005 he has been head of department for laser medicineat the Klinikum Berlin Neukölln now belonging to Vivantes. As head of department,he transferred the whole department to the Elisabeth Klinik Berlin in 2005 where hestill is. He is aFellow of the National German Academy for Technical Sciences (acatech), Fellow of the New York Academy
