System is provided for detecting the presence of an analyte of interest in a sample, said system comprising an elongated, transparent container for a sample; an excitation source in optical communication with the sample, wherein radiation from the excitation source is directed along the length of the sample, and wherein the radiation induces a signal which is emitted from the sample; and, at least two linear arrays disposed about the sample holder, each linear array comprising a plurality of optical fibers having a first end and a second end, wherein the first ends of the fibers are disposed along the length of the container and in proximity thereto; the second ends of the fibers of each array are bundled together to form a single end port.

L'invention porte sur un système pour détecter la présence d'un analyte d'intérêt dans un échantillon, ledit système comprenant un conteneur transparent, allongé, pour un échantillon ; une source d'excitation en communication optique avec l'échantillon, un rayonnement provenant de la source d'excitation étant dirigé sur la longueur de l'échantillon, et le rayonnement comprenant un signal qui est émis à partir de l'échantillon ; et au moins deux réseaux linéaires disposés autour du porte-échantillon, chaque réseau linéaire comprenant une pluralité de fibres optiques ayant une première extrémité et une seconde extrémité, les premières extrémités des fibres étant disposées le long de la longueur du conteneur et à proximité de celui-ci ; les secondes extrémités des fibres de chaque réseau étant regroupées ensemble pour former un orifice d'entrée unique.
