    • The invention relates to a fluorescent emulsion, to its uses and to labelling reagents comprising it. The fluorescent emulsion of the invention is of the oil-in-water type, comprising at least one aqueous continuous phase in which droplets of at least one oil phase are dispersed, said oil phase droplets being stabilized by a surfactant layer, characterized in that it comprises at least one pair of labels, differing from one another, formed from a donor fluorescent label that absorbs at a wavelength λ 1 and emits at a wavelength λ 2 different from λ 1 , and an acceptor label that absorbs at the emission wavelength λ 2 of the donor fluorescent label; in that the donor fluorescent label and the acceptor label are kept close together by the encapsulation of one of them in the oil phase droplets and either by linking the other of them to the oil phase droplet/aqueous phase interface, or by the encapsulation of the other of them in the oil phase droplets; and in that it comprises molecules of at least one amphiphilic surfactant and at least one solubilizing lipid. The fluorescent emulsion of the invention is applicable in the field of optical fluorescence imaging, in particular optical fluorescence biomedical imaging.
    • 本发明涉及荧光乳剂,其用途和标记包含它的试剂。 本发明的荧光乳液是水包油型的,其包含至少一个水相连续相,其中分散有至少一个油相的液滴,所述油相液滴由表面活性剂层稳定,其特征在于它 包含至少一对彼此不同的标签,由从波长λ1吸收并以与λ1不同的波长λ2发射的施主荧光标记形成,以及以发射波长λ2吸收的受主标记 的供体荧光标记; 因为供体荧光标记和受体标记通过将它们中的一个包封在油相液滴中并通过将另一个连接到油相液滴/水相界面而保持靠近在一起,或者通过将 其他的在油相液滴中; 并且其包含至少一种两亲性表面活性剂和至少一种增溶脂质的分子。 本发明的荧光乳剂可应用于光学荧光成像领域,特别是光学荧光生物医学成像领域。
