Cemitec presented results from Enviguard project at the Nanospain Conference on March 2017, a reference meeting of Nanoscience and Nanotechnology in Spain aiming to agglutinate and coordinate the efforts made in this field.

Paula Ciaurriz participated with an oral presentation about results achieved within WP4, the development of the Chemical Detection Unit (CDU): ‘Optical nanoimmunosensor based on periodic array of resonant nanopillars for real time detection of Okadaic Acid’.

The CDU is based on an optical sensor composed by photonic nanostructured surfaces (resonant nanopillars) as transducer and antibodies as bioreceptors. Through biofunctionalization of surface, specific recognition of targets is achieved. For this purpose, several strategies for bioreceptor immobilization and measurement protocol for okadaic acid have been developed and presented.Results show a limit of detection close to 5 ppb revealing the sensitivity of the sensor and pointing it out as a competitive analytical tool, since usually okadaic acid is determined by more complex and expensive techniques like chromatography.

Some results obtained within WP4 have been published in the scientific journal Sensors and Actuators B: Chemical in January 2017 under the title Optical sensor based on periodic array of resonant nanopillars for realtime monitoring”

Sensors and actuatorsSpecifically, the work performed at the laboratory scale with a preliminary optical set-up for the characterization of the optical transducer and its real time response has been reported.

The signal of the sensor was obtained with a common spectrophotometer by measuring light transmission through the resonant nanopillars surface. A flow-cell, connected to a peristaltic pump, was employed to load different refractive index solutions in order to assess the nanopillars bulk sensitivity and resolution (limit of detection). Excellent resolution and fluidic behavior were found, indicating the suitability of the resonant nanopillars system (WP4) for real time biosensing applications.

As the COMMON SENSE project comes to a successful conclusion, the results will be presented at a concluding workshop, along with a demonstration of the novel sensors developed and tested during the COMMON SENSE project. All stakeholders are invited to attend on 27 January 2017 in Barcelona.

The EnviGuard consortium met from the 8th to the 10th of November in Pamplona (Spain) in the 3rd Consortium Meeting. The meeting was organised by Centro Multidisciplinar de Tecnologías para la Industria, CEMITEC (www.cemitec.com), partner of the EnviGuard Project.

On behalf of S. Gruber, Head of Unit at European Commission DG RTD Björn Suckow was invited to represent the EnviGuard project at the AtlantOS workshop on Strategies, methods and new technologies for a sustained and integrated autonomous in-situ observing system for the Atlantic Ocean.

Björn Suckow (TTZ) presented and illustrated the results of the EnviGuard project during the thematic session at the 1stBlue Economy Business and Science Forum in Hamburg.

Deniz D. Tosun, Ferhat Çağıltay, Özkan Özden from Istanbul University Fisheries Faculty were invited to participated in the 2016 edition of the Middle East & Central Asia Aquaculture (MECAA-16) – “Towards sustainable aquaculture”

UNESCO has published the first ever global compendium on major harmful algal bloom (HAB), microorganisms that deplete fish stocks, destroy fish farms and bring disease and death both to humans and to large sea animals.

Dr Ian Johnston from the University of Hertfordshire presented EnviGuard project at the EuroScience Open Forum (ESOF) in Manchester on July 2016. The ESOF is a biennial, pan-European, general science conference dedicated to scientific research and innovation.

SEA-on-a-CHIP aims to develop a miniaturized, autonomous, remote and flexible immuno-sensor platform based on a fully integrated array of micro/nano-electrodes and a microfluidic system in a lab-on-a-chip configuration combined with electrochemical detection (impedimetric measurements) for real time analysis of marine waters in multi-stressor conditions.
