espanolHasta ahora se han tenido grandes avances en el area medica que conducen a diagnosticos mas exactos. pero la realidad es que aun falta mucho por hacer en cuanto al diagnostico oportuno y no invasivo. El detectar y caracterizar particulas pequenas, como los virus en el aire o bacterias en alimentos, es de suma importancia y se ha reportado que de entre las tecnicas de diagnostico y analisis de muestras biologicas existentes, aquellas que se basan en biosensores de guias de onda, presentan ventajas significativas como mayor resolucion, deteccion en tiempo real y son no invasivas. Las caracteristicas fisicas y geometricas de la guia de onda determinaran su utilidad en cada aplicacion. En este trabajo se presenta la metodologia para el modelado de guias de onda utilizando el software gratuito Metric; se modelaron guias de nitruro de silicio (Si3N4) con el fin de estudiar su potencial como biosensores EnglishCurrently there are numerous advances in the medical area that lead to more accurate diagnoses. However, there is an opportunity issue in terms of timely and non-invasive diagnosis. Detecting and characterizing small particles such as viruses in the air or bacteria in food is very useful, and it has been reported that among the existing diagnostic and analysis techniques for biological samples, those based on waveguide biosensor have significant advantages, such as higher resolution and real-time detecting. The physical and geometric characteristics of the waveguide will determine its usefulness in each application. This paper presents the methodology for modeling waveguides using the free software called Metric; Silicon nitride (Si3N4) waveguides were modeled to study their potential as biosensors. |
