Chemical sensors, technological

Over the last several years, the number of studies on application of artificial neural network for solving modeling problems in analytical chemistry and especially in optical fibre chemical sensor technology, has increase substantially69. The constructed sensors (e.g. the optical fibre pH sensor based on bromophenol blue immobilized in silica sol-gel film) are evaluated with respect to prediction of error of the artificial neural network, reproducibility, repeatability, photostability, response time and effect of ionic strength of the buffer solution on the sensor response. 

As opposed to conventional analytical techniques, optical sensors and biosensors, particularly those employing absorption and fluorescence-based sensing materials potentially allow for measurement through transparent or semi-transparent materials in a non-destructive fashion4, 5> 9 10. Chemical sensor technology has developed rapidly over the past years and a number of systems for food applications have been introduced and evaluated with foods.

The federal government must take the lead in supporting the research and development effort for ocean instrumentation because the government, through its agencies, is the beneficiary and ultimate consumer of most ocean measurements. Regardless of the approaches taken, it is clear that a considerable investment of time and resources will be required to develop the arsenal of chemically selective and stable host compounds that will be required to measure all the key oceanic species via in situ chemical sensor technology.

Of particular relevance to chemical sensor technology are the novel results of the electrochemical competition experiments. When an equimolar mixture ofNa+/K+orNa + /K + /Mg2 + cations is added to electrochemical solutions of (26), the ferrocene/ferricinium redox couple shifts anodically by an amount approximately the same as that induced by the K+ cation alone. This observation, together with the FABMS competition experimental findings, suggests that (26) is a first-generation prototype potassium-selective amperometric sensor, capable of detecting the K+ cation in the presence of Na+ and Mg2+ ions.

Potential applications of chemical sensors are diverse and numerous, and the environment where the sensor is used varies. Therefore, chemical sensor often requires to be tailor-made or semi-tailor-made to meet the needs in the special circumstance. For example, sensing of oxygen in an automobile exhaust or in water or in blood can be accomplished by using an electrochemical-based sensor. However, the selection of electrolyte and a diffusion-limited layer or protective membrane will be different in each case. Therefore, the platform chemical sensor technology is discussed in general. Special applications of a chemical sensor under a particular circumstance need to be addressed separately.
