    La importancia de las enfermedades cardiovasculares es de sobra conocida, responsables del 47 % de las muertes en Europa. Las mayoría de las patologías cardiovasculares estan causadas por una patología subyacente, como la aterosclerosis. El desarrollo de la placa es un proceso complejo, progresivo y asintomático hasta desembocar en un proceso isquémico. La placa vulnerable es aquella con alto riesgo de ruptura, generación de un trombo y proceso isquémico. En este proyecto desarrollaremos una herramienta basada en la nanotecnología para la identificación de la placa vulnerable a partir de suero de pacientes. Algunas de las propiedades del sensor que desarrollaremos son su sencillez de uso, sensibilidad y multifuncionalidad. Para ello emplearemos las propiedades ópticas de las nanopartículas de Oro, algo conocido y que ha sido explotado en muchos tipos de sensores in vitro. Sin embargo, nuestra aproximación será diferente a la habitual. Dadas las características dinámicas de la placa vulnerable no emplearemos un biomarcador para su detección, tampoco estudiaremos varios biomarcadores de forma secuencial para buscar correlaciones. Nuestra estrategia se basará en el uso de nanopartículas de oro funcionalizadas con hasta 4 anticuerpos diferentes de forma que puedan reconocer, en un solo paso, varios de los principales biomarcadores de la placa vulnerable. De esta manera no solo tendremos una sinergia en la respuesta óptica sino que podremos identificar la placa vulnerable independientemente del estadio en el que se encuentre. Para la puesta a punto de nuestro sensor se emplearán muestras de ratones ateroscleróticos y posteriormente se validarán con muestras humanas del biobanco del estudio PESA CNIC-Santander. Esta forma de hacer diana en la placa de forma múltiple es algo que no se ha intentado hasta la fecha y consideramos que ofrece una de las mejores opciones de identificación no invasiva de la placa vulnerable, algo para lo que hasta la fecha no existe solución.

    The importance of cardiovascular diseases is well known, accounting for 47 % of deaths in Europe. Most cardiovascular pathologies are caused by an underlying pathology, such as atherosclerosis. Plate development is a complex, progressive and asymptomatic process leading to an ischemic process. Vulnerable plaque is one with high risk of rupture, thrombus generation and ischemic process. In this project we will develop a nanotechnology-based tool for identifying vulnerable plaque from patient serum. Some of the sensor properties we will develop are its simplicity of use, sensitivity and multifunctionality. For this we will use the optical properties of gold nanoparticles, something known and which has been exploited in many types of in vitro sensors. However, our approach will be different from the usual approach. Given the dynamic characteristics of the vulnerable plate we will not use a biomarker for detection, nor will we study several biomarkers sequentially to search for correlations. Our strategy will be based on the use of functionalised gold nanoparticles with up to 4 different antibodies so that they can recognise, in one step, several of the main biomarkers of the vulnerable plate. In this way we will not only have a synergy in the optical response but we will be able to identify the vulnerable plate regardless of the stage in which it is. Samples of atherosclerotic mice will be used for the development of our sensor and subsequently validated with human samples from the biobank of the PESA CNIC-Santander study. This way of making multiple-shaped target on the plate is something that has not been tried to date and we consider that it offers one of the best options for non-invasive identification of vulnerable plaque, something for which to date there is no solution.
