This is the web site of the McDevitt group their interest is in “the science of hybrid molecular assemblies as applied to sensor and device applications”.
The McDevitt group has a research program developing lab-on-a-chip based technologies that are suitable for the rapid analysis of complex fluids. Their lab-on-a-chip research interests include non-invasive saliva diagnostics, cardiac risk assessment, HIV diagnostics and monitoring, bioterrorism screening tools, and environmental monitoring. Their web site gives details, including nice clear diagrams, of the methods behind their research areas. It is fully referenced with links to all the papers that the McDevitt group have published. Overall this is an interesting site to read about some of the developments in micro sensors.
Optics.org has resources and news for those involved in the lasers, optics and photonics industry. On searching for “chemical sensors” using the quotations marks to be more specific with the search and avoid irrelevant articles a number of links to short press release type articles were given. These then contained further links to their original sources. This site is a really big professional site with lots going on within it. You really need to know what you are looking for or you could be browsing for hours, so be specific and you will find something useful here. You do need to register (which is free) to obtain full articles and access to member only content.
This is the link to the sensor section of Pacific Northwest National Laboratory's Sensors & Electronics. From this homepage you can read about the chemical sensors that the staff use, the chemical sensor technology overview gives a useful insight into the theory and background of the sensors used. A full portfolio of the uses of their products is available and can be sorted by technical keyword which is useful. In the optical chemical sensing section the applications range from detection of water in organic solutions to a portable uranium assay instrument. This is a good site to have a browse of to see some possible applications of optical chemical sensors.
Ocean Optics is a supplier of solutions for optical sensing and spectroscopy, “fundamental methods of measuring and interpreting the interaction of light with matter”. Their vision is to “expand the frontiers of optical sensing and to make it the foundation on which innovative, life-changing ideas are built”. It is quite a big statement but there is a lot to see on this site. Admittedly it is a site that demonstrates and is there to promote their products but it still contains lots of useful information to read. The technical information is written by their engineers as a FAQ for users of Ocean Optics products. But the sample applications area is interesting to look at with links to external web sites including interesting applications from monitoring SO2 emissions from volcanoes to measuring optical properties of marine organisms. There is also a section on what OEMs and system integrators are doing with their systems.
