This system uses gratings (1200 g/mm) with several micron thick PDMS film on surface. Normally incident laser was coupled into a thin glass slide by grating coupling and confined in the slide due to the total internal reflection (TIR). The TIR generates evanescent planar wave on the glass surface. The evanescent wave was employed to excite the fluorescent signals in the microarrays. The method takes the advantages of low excitation background, large and uniform detection area.","PeriodicalId":346624,"journal":{"name":"The Second Asian and Pacific Rim Symposium on Biophotonics, 2004.

Currently SPR sensors are mainly based on measuring the angular shift associated with biomolecular adhesion. In fact it has been shown that the phase jump across the SPR dip is very steep, and consequently better sensitivity may be achieved by measuring the optical phase. In this presentation, we report interferometric techniques we have developed in our laboratory for achieving SPR phase detection. We also demonstrate that the incorporation of differential phase detection can further improve the performance of SPR biosensors. Currently the experimental sensitivity of our differential phase setup is 5.48/spl times/10/sup -8/ refractive index unit (RIU), which is three times better than that reported from conventional angular systems.","PeriodicalId":346624,"journal":{"name":"The Second Asian and Pacific Rim Symposium on Biophotonics, 2004.

Endoscopic techniques for evaluation and management of airway in pediatric patients have matured greatly in the past decade, especially with the introduction of Laser instrumentation. For example, to treat severe laryngomalacia, subglottic hemangioma, laryngeal papillomatosis, granuloma or web, subglottic or tracheal stenosis, bilateral vocal fold paralysis, tracheobronchial tumor etc. were all effective in selective cases. These developments have been proved that pediatric endoscopic laser surgery can be performed in the airway safely and effectively when a team approach is used. The appropriate choice of laser instruments, anesthesia access, post-operation intensive cares, cooperation and understanding of families were all essential factors for a successful endoscopic laser surgery in pediatric airway management.","PeriodicalId":346624,"journal":{"name":"The Second Asian and Pacific Rim Symposium on Biophotonics, 2004.
