Die Studie mit dem Titel „Investigation of bio-organic systems by means of optical techniques“ befasst sich im technischen Teil mit dem Aufbau und der Inbetriebnahme eines neuartigen Ramanspektrometers. Es wurden die wesentlichen Leistungsparameter des Systems untersucht und mit Erwartungen aus Simulationen verglichen. Ausserdem wurde eine Systemintegration mit Lichtquellen, Strahlengang und Justageprozeduren durchgeführt. Weiterhin beschäftigt sich diese Arbeit mit den Möglichkeiten optischer Untersuchungsmethoden bezüglich keratinbasierter bio-organischer Materialien. Mittels spektroskopischer Ellipsometrie wurde neben allgemeinen Charakterisierungsuntersuchungen eine Studie der Hydrationsdynamik von Fingernägeln durchgeführt. Die Ergebnisse dieser Studie wurden mit einem Modell bestehend aus ,,freiem`` und ,,gebundenem`` Wasser erklärt. Die Ellipsometrie wurde auch für eine in-vivo Tapestripping Studie verwendet, welche ein Tiefenprofil des stratum corneums lieferte und aufzeigte, das Depolarisationseffekte eine grosse Rolle bei der Ergebnisinterpretierung spielen und in Zukunft weiter untersucht werden sollten. Das neue Ramanspektrometer wurde ebenfalls für biophysikalische Untersuchungen eingesetzt. Im tiefen UV bei 244 nm wurde eine Zerstörungsstudie an Einzelhaaren und eine Studie an Hautbiopsien durchgeführt. Motivation für Messungen in diesem Wellenlängenbereich sind Fluoreszenzuntersuchungen im Sichtbaren sowie eine ebenfalls durchgeführte Raman-Resonanzstudie an destilliertem Wasser im Wellenlängenbereich zwischen 631 und 237 nm. Während der Studien wurden die technischen Grenzen beider optischer Aufbauten offenbar und führten u. a. zu dem Design eines neuen Periskops für das Ramanspektrometer, um die Probenpositionierung zu verbessern. Außerdem wurden durch die Ellipsometriemessungen Grundlagen zum Aufbau eines neuartigen, speziell an biologische Systeme angepassten Ellipsometers gelegt.

Download Frontiers in Biosensorics I Book in PDF, Epub and Kindle
Volume I provides an in-depth discussion of the most recent developments of crucical biosensor components. It concentrates on the interface between the analyte phase and the detector, namely, the implementation of novel recognition elements, including nucleic acids, and of leading-edge technology in the construction of responsive thin layers. Thus, the reader can obtain a foretaste of achievable future progress in the field.

Download Optical Chemical Sensors Book in PDF, Epub and Kindle
This book covers optical chemical sensing by means of optical waveguides, from the fundamentals to the most recent applications. The book includes a historical review of the development of these sensors, from the earliest laboratory prototypes to the first commercial instrumentations. The book reprints a lecture by the Nobel Laureate Charles Townes on the birth of maser and laser, which lucidly illustrates the development of new science and new technology.

Download Sol-Gel Processing and Applications Book in PDF, Epub and Kindle
During my professional career, I developed a strong interest in sol-gel technology, and worked on both xerogel and aerogel systems. My fascination with aerogels has driven me to explore their commercial potential, which is currently an important component of my company's business plan. Together with my co-workers, I have also worked on the preparation of controlled PZT and silica xerogels as well as thin film coatings of metals by the sol-gel technology, These experiences convinced me of the tremendous potentials of this technology. A conviction that is shared by many scientists, engineers, and business leaders around the globe. Many sol-gel derived products are already articles of commerce. However, to expand the commercial potential of sol-gel technology, two challenges must be met: (1) the quality of sol-gel derived products must continue to meet or exceed the quality of competing products, (2) the production cost of sol-gel products (specially aerogels) must continued to decline. A key to lowering the costs of sol-gel products is finding inexpensive precursors.
