    Note: Während meiner Vorlesungen zur molekularen Photobiophysik wurde ich immer wieder von Studenten nach einer einführenden Literatur zu diesem Problemkreis gefragt, die es jedoch im engeren Sinne bisher nicht gibt. Natürlich liegt eine Vielzahl von Büchern und Übersichtsartikeln zu einzelnen fachspezifischen Fragestellungen vor. Allein die Literatur zur Photosynthese aus biologischer, bioenergetischer, physikalischer oder biochemischer Sicht ist kaum mehr zu überschauen und nimmt ständig an Umfang zu. Ebenso existieren eine Reihe von Standardwerken zur optischen Spektroskopie oder anderen in diesem Buch angesprochenen Problemkreisen. Dennoch ist es für den Neuling auf dem Gebiet der Photobiophysik nahezu unmöglich, sich in angemessener Zeit einen Überblick über die Vielfalt des für eine erfolgreiche Arbeit notwendigen Rüstzeugs zu verschaffen. Dies wird nicht zuletzt durch die noch immer gängige Studienpraxis der strengen Unterteilung der Naturwissenschaften in die "reine" Physik, Chemie, Biologie usw. an den Universitäten erschwert. Deshalb habe ich nach fast 20jähriger Lehrtätigkeit, dem Drängen meiner Studenten folgend und ermutigt durch meine Mitarbeiter und Kollegen, begonnen, eine Einführung in die molekulare Photobiophysik zu schreiben. Ziel dieses Buches ist es keinesfalls, dem Gros der einschlägigen Standardwerke zu dem einen oder anderen Problem ein weiteres Werk hinzuzufügen, weshalb solche Themen wie z. B. die Photosynthese bewußt nicht im Mittelpunkt der Betrachtung stehen, sondern in den Kontext einer allgemeinen Sicht auf die Problematik der molekularen Photobiophysik eingebunden werden. In dieser Einführung habe ich versucht, die aus meiner Sicht zum derzeitigen Zeitpunkt wesentlichen Aspekte der molekularen Photobiophysik möglichst übersichtlich und ausgewogen zu behandeln. Das schließt natürlich eine gewisse Subjektivität ein

    Content: Biofouling is one of the most serious problems in membrane filtration systems for water treatment. An easily applicable antimicrobial finish of polyethersulfone (PES) filter membranes is shown by derivatizing an approved chlorin photosensitizer drug with adhesive ortho-catechol functionalities as known from l-3,4-dihydroxyphenylalanin (Dopa) residues of marine mussel glues. The chemical structure of the second-generation photosensitizer 5,10,15,20-tetrakis(3-hydroxyphenyl)chlorin (m-THPC) is modified by 2-iodoxybenzoic acid (IBX) oxidation, transforming the peripheric meta-phenols of m-THPC into ortho-catechols, and thus improving the adsorption properties of m-THPC derivatives onto PES material. Stable coatings are formed that preserve chlorin's capability to generate singlet oxygen under visible light illumination. The modification of one or two phenol groups out of the four m-THPC substituents leads to an optimum in the generation of active singlet oxygen, and thus the finish significantly reduces the bacterial growth of gram-negative Escherichia coli and gram-positive Micrococcus luteus on the PES membranes.

    Content: Singlet Oxygen, the lowest electronically excited state of molecular oxygen, is highly reactive and involved in many chemical and biological processes. It is one major mediator during photosensitization, which has been used by mankind since ancient times, even though the mechanisms behind it were understood only about half a century ago. The combination of high reactivity and very long natural lifetime allows for direct optical detection of singlet oxygen and its interactions using its characteristic phosphorescence at around 1270 nm. Since this emission is very weak, optical detection was technically very challenging for a long time. Therefore, even today, most laboratories only exploit the high reactivity to observe the interaction with sensor molecules, rather than singlet oxygen emission itself. However, in recent years highly sensitive optical detection was developed, the authors being major contributors. This book is dedicated to the detection of singlet oxygen, discussing possibilities, pitfalls and limits of the various methods with a special focus on time-resolved phosphorescence and the kinetics of singlet oxygen generation and decay including involved and related processes, discussing investigated systems with various complexity from solutions over in vitro to in vivo. The long-standing paradigm that singlet oxygen phosphorescence is a benchmark for detection systems rather than an option for process observation is still ubiquitous and this book hopes to contribute in overcoming this still prevailing bias.
