The interest in finding reliable and highly sensitive sensors for water quality control has grown recently empowered by the explosion of cutting-edge technologies such as nanotechnologies, optoelectronics, and computing on one hand and by the increasing need for more secure control of water quality on the other hand. This book highlights a number of modern topics in the field of biosensing particularly for water sensing in which the signal is enhanced, starting from surface enhanced spectroscopies using plasmonic structures such as Raman scattering (SERS), infrared enhanced absorption (SEIRA), and surface enhanced fluorescence (SEF). The SPR enhanced detection is highlighted in two chapters and addressed using signal processing and the use of color of solutions as a result of modification of the LSPR properties of nanoparticles. Porous materials are another field of research where the enhancement is achieved due to the increasing the area- to-volume ratio. Good examples are the two emerging fields of porous Si and sculptured thin films prepared by the oblique deposition technique. One of the long standing problems is bacteria detection in water which is addressed thoroughly with emphasis on the problems usually encountered in detecting large bioentities.

Nanophotonics is a newly developing and exciting field, with two main areas of interest: imaging/computer vision and data transport. The technologies developed in the field of nanophotonics have far reaching implications with a wide range of potential applications from faster computing power to medical applications, and "smart" eyeglasses to national security.

"Integrated Nanophotonic Devices" explores one of the key technologies emerging within nanophotonics: that of nano-integrated photonic modulation devices and sensors. The authors introduce the scientific principles of these devices and provide a practical, applications-based approach to recent developments in the design, fabrication and experimentation of integrated photonic modulation circuits.

For this second edition, all chapters have been expanded and updated to reflect this rapidly advancing field, and an entirely new chapter has been added to cover liquid crystals integrated with nanostructures.
Unlocks the technologies that will turn the rapidly growing research area of nanophotonics into a major area of commercial development, with applications in telecommunications, computing, security, and sensing Nano-integrated photonic modulation devices and sensors are the components that will see nanophotonics moving out of the lab into a new generation of products and servicesBy covering the scientific fundamentals alongside technological applications, the authors open up this important multidisciplinary subject to readers from a range of scientific backgrounds
