3. AWACSS (EVK1-CT-2000-00045)ENVSENS, Lecce, Italy, 2002 Goal: Develop a cost-effective, on-line, water monitoring biosensor that will measure a variety of small organic pollutants in short-time with remote control and surveillance. Expanded multi-analyte analysis capability allowing for up to 32 simultaneous analyte measurements. Immunochemical reagents are being developed for a host of small organic water pollutants. Novel design approaches to the optical detection and fluidics including miniturized integrated optics and microfluidics. Reduced reagent volumes. Limits of detection matching EU prescribed requirements (~1 ppb). Intelligent remote surveillance and control that will allow for unattended continuous monitoring. Instruments will be rugged and easy to handle by untrained personnel.

7. AWACSS (EVK1-CT-2000-00045)ENVSENS, Lecce, Italy, 2002 Instrument Design 1st Year Goal: Design and order the equipment necessary to assemble the AWACSS instruments. Progress: Microfluidics designed with preliminary testing: small volumes & Poiseuille flow. Designed or selected pumps, valves, lasers, detectors, power supplies, filters, circuit boards, computers. Autosampler chosen. Preliminary testing of electronics.

8. AWACSS (EVK1-CT-2000-00045)ENVSENS, Lecce, Italy, 2002 Integrated-Optical (IO)-Chip Development Goal: Develop IO-Chips capable of simultaneously illuminating 32 analysis windows in a miniaturised format. Advantages: Single mode waveguides allow for efficient and consistant analysis window illumination. Compact dimensions allow for microfluidic design and reduce sample & reagent volumes. Spatially defined but resolved analysis windows allow efficient detection and suppress signal crosstalk. Progress: Protype IO-Chips have been designed and fabricated. Preliminary tests are now being carried out.
