Konferensbidrag (refereegranskat)abstract
- LIDAR techniques are used to measure gases in solid scattering media remotely, by analyzing the differential absorption observed in the multiple scattering light. The gas exchange (O-2/N-2) in polystyrene foam is monitored. (C)2008 Optical Society of America

Ingår i: Asia Optical Fiber Communication and Optoelectronic Exposition and Conference 2008. - : Optical Society of America. - 9781557528636
-
Konferensbidrag (refereegranskat)abstract
- Enhancement of fluorescence of streptavidin conjugated with gold nanorods (GNRs) was observed. The impact of GNRs with different surface plasmon resonance bands and different concentrations to the efficiency of the fluorescence enhancement was studied.

Konferensbidrag (refereegranskat)abstract
- We investigate the lag-effect in the dry etching process. In one etch step, asymmetric waveguides with a shallow groove in between can be fabricated. This special property can be utilized for the design of an ultra-compact polarization insensitive directional coupler.

Diagnostics and Treatment of Tumours using Laser Techniques

Konferensbidrag (refereegranskat)abstract
- Laser spectroscopy techniques can be used for tumour detection as well as for localised therapy of malignancies. Laser-induced fluorescence with or without exogenously administered tumour seeking agents is a promising technique for real-time detection of atypical cells and dysplasia before the diseased areas can be visualised by the naked eye. Tumour borders can also be delineated towards normal non-affected tissue with the same technique. Gas in scattering media absorption spectroscopy can be used for monitoring gas contents in hollow organs in the human body, such as the sinuses in the facial area. Photodynamic therapy utilising red laser light and photosensitising agents is a selective treatment modality for certain types of thin malignancies. By using optical fibres inserted into the tumour mass deep lying tumours can also be treated. (C) 2008 Optical Society of America
