Para ello el sistema se compone de dos partes:<\/p>\n<p>La primera de ellas son unos <a href=\"http:\/\/www.technologyreview.com\/biomedicine\/22014\/?mod=related\">nanosensores<\/a> introducidos en forma de &#8220;tattos&#8221; en la piel. Debido a su carga el\u00e9ctrica, se adhieren las part\u00edculas del intersticio con carga opuesta. Una vez fijadas, los nanosensores liberan iones convirtiendo la carga en neutra y emitiendo fluorescencia al ser excitados mediante luz. Cuantas m\u00e1s part\u00edculas del tipo haya en la sangre, mayor ser\u00e1 el n\u00famero de part\u00edculas adheridas a los &#8220;tattos&#8221; y mayor ser\u00e1 la fluorescencia observable.<\/p>\n<p>La segunda parte consiste en un iPhone modificado a el que se le ha puesto una carcasa con una bater\u00eda, tres LEDs que emiten radiaci\u00f3n en el espectro visible (luz blanca) y un filtro \u00f3ptico para el sensor de la c\u00e1mara del iPhone que no deja pasar la luz emitida por los LEDs pero si la luz fluorescente emitida por el tatto. Para que funcione bien, la carcasa del iPhone debe estar completamente pegada a la piel para evitar que la luz exterior falsee la medici\u00f3n. El iPhone\u00a0entonces recoge la imagen y analiza el porcentaje de fluorescencia, calculando as\u00ed la concentraci\u00f3n en sangre de las part\u00edculas bajo estudio.<\/p>\n<p><a title=\"Art\u00edculo completo\" href=\"http:\/\/www.technologyreview.com\/read_article.aspx?id=38065&amp;a=f\" target=\"_blank\">Enlazamos el art\u00edculo<\/a> de Technology Review.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Un grupo de investigaci\u00f3n del departamento de ciencias farmacol\u00f3gicas de la Universidad de Northeastern ha dise\u00f1ado un sistema basado en nanosensores para detectar niveles de sodio (deshidratacion), glucosa, cloro, as\u00ed como ox\u00edgeno en sangre.
