At the end of June this year the LASER World of PHOTONICS took place in Munich, Germany. With 1.293 exhibitors and more than 32.000 visitors from 90 countries, it is the world’s leading photonic trade fair. One of the exhibitors was MULTITEL ASBL from Belgium and consortium member of the FP7 project EnviGuard.
Thanks to the Newsletter and the dissemination of all EnviGuard partners, people stopped at the MULTITEL booth to get more information about the EnviGuard project and showed interest in the different challenges that we are facing within the scope of this multidisciplinary project. Even people from New Zealand came, because they would like to implement something similar at their coasts as an early warning system.
In parallel to the trading fair, the World of Photonic Congress took place with about 3.500 attendees. Part of this congress was the CLEO/Europe-EQEC conference, where MULTITEL had the chance to present a poster showing results of the EnviGuard project. MULTITEL has developed within WP4-the chemical detection unit a multichannel spectrometer to analyze the quantity of the chemicals PCB 169 and 126, okadaic acid and saxitoxin detected by the multiplexed sensor chip.
The poster attracted interested people from different continents (Asia, Australia, Europe, and North America) with an interested in the spectrometer itself like an engineer from Newport or about the surface functionalization in order to specifically detect certain toxins as an engineer from the University of Montpelier asked.
The spectrometer was also part of a demonstration setup at our booth where we were able to show prospective customers the operation of the spectrometer including a figure of a sensogram.
EnviGuard had a successful day at the Oceans of Tomorrow workshop held as part of the MTS/IEEE Oceans’ 17 Aberdeen Scotland exhibition and conference held 21-22nd June. ENVIGUARD was presented in a Power Point slide during 20mins plus 10 mins questions. There were presentations from several similar projects funded under the FP7 ‘Oceans of Tomorrow’ programme, these were:
SENSEOCEAN - Development of biogeochemical sensors for autonomous platforms and observatories
BRAAVOO - Biosensors for Near Real-Time Marine Toxicant Monitoring
SMS - Innovations in emerging pollutants ocean monitoring using biosensing technology
SCHeMA - Integrated In situ CHemical MApping probes: objectives and main achievements
NeXOS - Development and end-to-end integration of compact, low-power, multifunctional ocean sensors.
ENVIGUARD - Advances in biosensor technology for monitoring harmful algae, algae toxins & PCB
MariaBox - first prototype of a novel instrument to observe natural and chemical pollutants in seawater
COMMON SENSE - Cost-effective sensors, interoperable with international existing ocean observing systems
Several of these projects overlap to some degree with ENVIGUARD, to a greater of lesser degree – in particular SMS. Most of the projects are developing sensors for chemical contaminants including algal toxins and inorganics, algal detection and environmental parameters. It seems that ENVIGUARD is the only project investigating a sensor to detect microbial and viral pathogens in the water column (though this part of the project was not discussed in the presentation by Dennis Gowland).
A common theme from the researchers involved was to achieve real time sampling in-situ – often from buoys. Challenges remain to ensure that prototypes are made robustly to survive in offshore marine conditions.
Degrees of readiness (Technological Readiness Level – RTL) ranged from TRL4 (lab validation) to (in rare cases) TRL9 (System test, launch & operations). Mostly the projects reported TRL 4-8.
During Question & Answer sessions and at a Panel session at the end of the workshop it was emphasised that the new technologies and the new methods of deployment developed in the projects would need an extended period of demonstration would be required to satisfy the requirements of the market and that standards (where not already existing) would need to be addressed.

The CLEO®/EUROPE - EQEC (Conference on Lasers and Electro-Optics - European Quantum Electronics Conference) is an event that will take place in the scope of the LASER World of PHOTONICS, which is the world wide leading fair for the Laser and Photonic industry which takes place every two years in Munich since 1973. In 2015 there have been 1130 exhibitors from 42 different countries and 31.279 visitors from 72 countries. At the CLEO 3900 people participated and there have been more than 2700 presentations and posters. This year there will be more than 1700 presentations. You can check the full program here.
In the framework of this event, there will be a poster session, where EnviGuard poster will be presented on Tuesday June 27 from 1 pm. until 2 pm. in Hall B0, gound floor, Congress Centre. The poster title is "A compact, high Resolution Multichannel Optical Interrogator based on an Integral Field Spectrometer for Label-free Monitoring of Toxins in Oceanic Water", Hendrik von Hörsten, Sébastien Guillemet, Nicolas van Impe, Maxime Denti, Giselle Fernandes, Fabian Dortu, Yves Hernandez, Iñaki Cornago, Paula Ciaurriz, Edurne Teiletxea, Fátima Fernandez.

On 16th of May, TTZ participated in the final meeting of the SEA-on-a-CHIP project, one of the sister projects from EnviGuard. The event took place in Olhão, Portugal. The event aimed to increase the international visibility of the project results and those of the attending sister projects. It was also meant to establish relationships to the invited end users, authorities and other EU-funded projects in related areas.
During a visit at the Portuguese Institute of Sea and Atmosphere’s (IPMA) aquaculture pilot station (EPPO) the 3rd prototype of SEA-on-a-CHIP biosensor system was shown in “modus operandi” in situ. During the marine biosensor session of the open technical workshop of the meeting, Björn Suckow presented the latest results of the EnviGuard project.
For this technical workshop, it was submitted an abstract which was published in the book of abstracts of the meeting under the title "EnviGuard – Advances in biosensor technology for monitoring harmful algae, algae toxins & PCB" that you can read here.

The International Innovations Workshop aquaculture took place the last 14th of March in Berlin (Germany), with the goal of presenting the diversity of the innovative technology and transfer potentials from the marine aquaculture environment in Germany in an international context.
During this one-day, English-speaking event, discussions took place with selected experts from other European countries to create strategic alliances. The event also represented a first milestone for the preparation of the international aquaculture conference "Aquaculture Europe 2019" of the European Aquaculture Society (EAS), which will be held in Berlin in two years (07. - 10 October 2019).
EnviGuard was discussed in the session “New approaches to unlock the potential of off-shore aquaculture”. A dedicated session of biosensors in Aquaculture was proposed.
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.
You can find out more about this event here.
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”
Specifically, 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.
