Environmental biosensors: a status report

Article Abstract:

Biosensors are slowly gaining acceptance as reliable tools in the environmental analytical community. More and more instruments and methods are being developed for environmental applications, especially those requiring continuous, in situ monitoring. Biosensors are undergoing field-testing and are nearing commercialization in the US, Europe and Japan. Biosensors hold much promise in environmental applications due to their ability to measure the interaction of pollutants with biological systems. They can also regenerate and reuse the immobilized biological recognition element, unlike bioanalytical assays.

New instrument brings PAH analysis to the field

Article Abstract:

The field-portable scanning spectrofluorometer (FPSS) is a new instrument developed by environmental scientists to analyze polyaromatic hydrocarbons (PAHs) and other high molecular organic compounds in the field. FPSS uses a synchronous scanning capability that takes advantage of the overlap between the emission and absorption spectra of a particular compound. Testing of a prototype instrument in the laboratory showed the significant correlation of FPSS data with GC-mass spectrometry results.

A status report on field-portable immunoassay

Article Abstract:

Immunoassay test kit manufacturers currently offer a wide range of field-portable systems to meet the needs of the environmental analytical community. However, efforts to develop even better immunoassays for both laboratory and field applications continue, with manufacturers, regulatory agencies and chemical firms collaborating towards this end. A brief overview of the most recent developments in immunoassay kits is presented.
