Rao G. (Ed.). Optical Sensor Systems in Biotechnology

Springer, 2009. - 171 p. - In this volume, several frontier articles assess the latest approaches to measure a variety of parameters. Lam and Kostov start out with a survey of instrumentation that is enabling low-cost optical sensors to become a reality. The consumer electronics revolution, coupled with low-cost LED (and laserdiode) sources that have replaced bulky lasers, is the key to making compact devices that rival the performance of expensive laboratory systems. Ray et al. review the unique behavior of light-excited surface plasmons and the resulting coupling to fluorescence in proximity to metal substrates.
