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.
