    EN ESTE PROYECTO SE PROPONE LA PUESTA EN MARCHA DE NUEVAS TECNOLOGIAS QUE PERMITIRAN DETECTAR Y MONITORIZAR AMENAZAS RECIENTEMENTE IDENTIFICADAS EN EL MEDIO MARINO ASOCIADAS A (I) LA ACUMULACION DE CONTAMINANTES MOLECULARES EN LA INTERFASE DEL MEDIO MARINO, (II) LA PRESENCIA DE NANOPARTICULAS INORGANICAS EN DICHO MEDIO, Y (III) LA APARICION DE CELULAS CANCERIGENAS TRASMISIBLES ENTRE ESPECIES MARINAS. DICHAS ESTRATEGIAS SE BASAN EN EL USO DE NANOESTRUCTURAS PLASMONICAS Y MAGNETICAS, LAS CUALES POSIBILITARAN UN SEGUIMIENTO EFICIENTE DE ESTAS NUEVAS AMENAZAS._x000D_ EN EL PRIMER CASO, SE PLANTEA EL DESARROLLO DE UN DISPOSITIVO CAPAZ DE LLEVAR A CABO UNA DETECCION OPTICA ULTRASENSIBLE EN LA INTERFASE AIRE-AGUA MEDIANTE EL EMPLEO DE ESPECTROSCOPIA RAMAN AUMENTADA POR SUPERFICIE (SERS), A DIA DE HOY, UNA DE LAS TECNICAS ANALITICAS DE MAYOR SENSIBILIDAD. EN EL SEGUNDO CASO, SE PROPONE EL APROVECHAMIENTO DEL FENOMENO DE INYECCION DE ELECTRONES (HOT ELECTRON) ENTRE METALES Y SEMICONDUCTORES, LO QUE PROPORCIONARA UN ALTO GRADO DE SENSIBILIDAD EN LA DETECCION DE CONTAMINANTES NANOPARTICULADOS. EN EL TERCER CASO, SE PLANTEA EL USO DE NANOESTRUCTURAS MAGNETICAS COMO AGENTES DE CONTRASTE PARA IMAGENES DE RESONANCIA MAGNETICA (MRI), CON EL FIN DE MONITORIZAR LA RUTA DE TRANSMISION DE CELULAS NEOPLASICAS MEDIANTE SU MARCAJE. LA INFORMACION OBTENIDA EN ESTOS ESTUDIOS, SERA DE VITAL IMPORTANCIA DESDE UN PUNTO DE VISTA MEDIOAMBIENTAL Y ECONOMICO._x000D_ ASI, EL OBJETIVO FINAL DE NANOMARE ES EL DE DESARROLLAR ESTRATEGIAS DE IDENTIFICACION Y MONITORIZACION COMPLETAMENTE NUEVAS, BASADAS EN EL USO COMBINADO DE LA NANOQUIMICA, LA CATALISIS, EL RECONOCIMIENTO MOLECULAR, LA BIOFUNCIONALIZACION, EL SERS Y EL MRI. ESTE INNOVADOR ENFOQUE, INTER- Y MULTIDISCIPLINAR, BUSCA PONER EN MARCHA METODOLOGIAS UNICAS PARA LLEVAR A CABO MEDIDAS IN SITU, PRECISAS Y EN TIEMPO REAL DE CONTAMINANTES DE ORIGEN ANTROPOGENICO Y OBTENER INFORMACION ACERCA DEL PROCESO DE TRANSMISION DE CELULAS TUMORALES ENTRE BIVALBOS. COMO RESULTADO, ESTE PROYECTO IRA MAS ALLA DE LAS TECNOLOGIAS DE VANGUARDIA EN EL CAMPO DE LA DETECCION DE CONTAMINANTES INORGANICOS Y BIOLOGICOS EN EL MEDIO MARINO. (Spanish)

    WE PROPOSE HEREIN THE IMPLEMENTATION OF NOVEL TECHNOLOGIES THAT WILL ALLOW DETECTING AND MONITORING EMERGING THREATS IN MARINE ENVIRONMENTS ASSOCIATED TO (I) THE ACCUMULATION OF MOLECULAR POLLUTANTS IN THE AIR-WATER INTERFACE, (II) THE PRESENCE OF INORGANIC NANOPARTICLES IN WATER BODIES, AND (III) THE APPEARANCE OF TRANSMISSIBLE CANCER CELLS BETWEEN MARINE SPECIES. THESE STRATEGIES ARE BASED ON THE USE OF PLASMONIC AND MAGNETIC NANOSTRUCTURES THAT WILL MAKE POSSIBLE AN EFFICIENT MONITORING OF THESE NEW THREATS._x000D_ IN THE FIRST CASE, WE ADDRESS THE DEVELOPMENT OF A DEVICE ENDOWED WITH OPTICAL ULTRASENSING CAPABILITIES IN THE AIR-WATER INTERFACE BY USING SURFACE-ENHANCED RAMAN SPECTROSCOPY (SERS), ONE OF THE MOST POWERFUL ANALYTICAL TECHNIQUES NOWADAYS. IN THE SECOND CASE, WE PROPOSE THE EXPLOITATION OF THE HOT-ELECTRON INJECTION MECHANISM BETWEEN METALS AND SEMICONDUCTORS, WHICH WILL PROVIDE A REMARKABLY LOW LIMIT OF DETECTION OF NANOPARTICULATE POLLUTANTS. IN THE THIRD CASE, WE ADDRESS THE USE OF MAGNETIC NANOSTRUCTURES AS MAGNETIC RESONANCE IMAGING (MRI) CONTRAST AGENTS, AIMING AT MONITORING THE TRANSMISSION PATHWAY OF NEOPLASIC CELLS BY LABELING. ALL THE INFORMATION OBTAINED THROUGH THESE DIFFERENT METHODOLOGIES WILL BE OF PARAMOUNT IMPORTANCE FROM AN ENVIRONMENTAL AND ECONOMIC POINT OF VIEW._x000D_ THUS, THE FINAL GOAL OF NANOMARE IS THE DEVELOPMENT OF CUTTING-EDGE STRATEGIES FOR DETECTION AND MONITORING OF MARINE THREATS, BASED ON THE COMBINED USE OF NANOCHEMISTRY, CATALYSIS, MOLECULAR RECOGNITION, BIOFUNCTIONALIZATION, SERS AND MRI. THIS INNOVATIVE INTER- AND MULTIDISCIPLINARY APPROACH SEEKS FOR THE IMPLEMENTATION OF UNIQUE METHODOLOGIES TO PERFORM REAL-TIME, IN SITU, AND PRECISE MEASUREMENTS OF ANTHROPOGENIC CONTAMINANTS IN WATER BODIES, AS WELL AS GAINING INSIGHTS INTO THE CANCER CELL TRANSMISSION BETWEEN BIVALVE SPECIES. AS A RESULT, THIS PROJECT WILL GO BEYOND THE CURRENT LEADING TECHNOLOGIES IN THE FIELD OF DETECTION OF INORGANIC POLLUTANTS AND BIOLOGICAL THREATS IN MARINE ENVIRONMENTS. (English)
