Special Issue: Sensors for Environmental Monitoring

This paper surveys the needs associated with environmental monitoring and longterm environmental stewardship. Emerging sensor technologies are reviewed to identify compatible technologies for various environmental monitoring applications. The contaminants that are considered in this report are grouped into the following categories: (1) metals, (2) radioisotopes, (3) volatile organic compounds, ...

Special Issue Preface, DNA Based Sensors

DNA-based sensors belong to chemical sensors used in chemical/biochemical analysis. Among the biosensors generally, there are some specific features at these sensors regarding their use to the investigation of DNA itself, both its amount (concentration) and chemical/biochemical reactivity. With respect to this, the DNA biosensors represent irreplaceable testing devices. From the discovery of el...

PAPER Special Issue on Optical Fiber Sensors

distributed sensings on temperature and strain have been extensively investigated based on Raman [1] and Brillouin [2] scattering methods, respectively. During the course of our developments on a new sensor which can work as one of sensing elements for multi-point detection using a Rayleighscattering based OTDR through an optical fiber network, a hetero-core fiber optic sensor was exploratively...

Special Issue of Photonic Sensors for Chemical, Biological, and Physical Parameter Detection

Photonic sensors have been developed for use in many laboratory and industrial environments for detection of a wide variety of physical, biological and chemical parameters. Both free space and guided wave optical sensors have been demonstrated for use in such diverse applications as food processing, electric power generation, jet engines, oil production, radiation detection, chemical and biolog...
