In this paper a overview is presented with respect to chemical sensors. First general sensor concepts aie described. In addition a number of applications with two cases are given, one for the automobile emission control and one for the (bio)chemical sensor in order to illustrate the interesting field of chemical sensors.

Graphene-Based Chemical Sensors
The Journal of Physical Chemistry Letters, 2012Pioneering research in 2004 by Geim and Novoselov (2010 Nobel Prize winners in Physics) of the University of Manchester led to the isolation of a monolayer graphene sheet. Graphene is a single-atom-thick sheet of sp(2) hybridized carbon atoms that are packed in a hexagonal honeycomb crystalline structure.

Holographic chemical vapor sensor
Optics Letters, 2005A holographic interferometer senses vapor-induced optical path length changes in polymer or other chemically sensitive films. The interferometer is inherently sensitive to changes in chemical vapor content, self-compensates for drifts, and accommodates a large array of sensor elements. A sniff-locked-loop synchronous detection method takes advantage of

Frequency-Coded Chemical Sensors
Analytical Chemistry, 2007We have developed a new method to intelligently sample analytes and introduce the analytes to sensors. The method automatically adjusts sampling duration according to the sensors' response to the analytes and converts the amplitude of the sensor output to a frequency output, giving us another opportunity to reduce noise in the signal. It also addresses

Waveguides as chemical sensors
Analytical Chemistry, 1989The purpose of this article is to demonstrate the breadth of applications served by waveguides as chemical sensors and to provide a brief tour of current implementation techniques. After a short review of how waveguides work, some current case histories are presented dealing with practical analytical situations that may help stimulate problem solving.
