Abstract
Se proporcionan métodos y sistemas para la espectroscopia Raman resonante. Los métodos de acuerdo con ciertas modalidades incluyen la irradiación de una muestra con una fuente de luz monocromática a una primera intensidad de irradiación y una segunda intensidad de irradiación, determinar la intensidad de una o más dispersiones Raman resonante y dispersión de fluorescencia en la primera intensidad de irradiación y la segunda intensidad de irradiación, calcular una tasa de cambio de uno o más de la intensidad de la dispersión Raman resonante y fluorescencia en respuesta al cambio en la intensidad de irradiación desde la primera intensidad de irradiación a la segunda intensidad de irradiación y comparar uno o más de la tasa de cambio en la intensidad de la dispersión Raman resonante y la tasa de cambio en la intensidad de la dispersión de fluorescencia con la tasa de cambio en la intensidad de irradiación por la fuente de luz monocromática para determinar la respuesta Raman resonante de la muestra. Los métodos también incluyen determinar la presencia o ausencia de un microorganismo en una muestra y corregir las variaciones asociadas con la instrumentación de medición (por ejemplo, fuente de luz monocromática) y las variaciones asociadas con la muestra (por ejemplo, fluorescencia de compuestos no objetivo). También se proporcionan métodos para determinar la susceptibilidad antimicrobiana de un microorganismo a un agente antimicrobiano, así como métodos para caracterizar un fenotipo de un microorganismo desconocido en una muestra. También se proporcionan sistemas para practicar los métodos de la materia.
