The present invention relates to methods of visualising cells especially although not exclusively in vivo using a dye, such as a dendrimer-dye molecule or polybranched-dye molecule which is internalised by the cells and thus permits subsequent visualisation by confocal fluorescence endomicroscopy or other optical detectors. There is also provided internally quenched probes for use in visualising cells especially although not exclusively in vivo by confocal fluorescence endomicroscopy and the use of internally quenched probes in combination with confocal fluorescence endomicroscopy, for visualising cells by virtue of internalisation and dequenching of a probe by the cells. In a particular embodiment the cells are activated neutrophils, such as within the lung of a subject.
本发明涉及一种在体内使用染料(例如树枝状染料分子或多支化染料分子)来可视化细胞的方法,尤其是通过共聚焦荧光内窥镜或其他光学探测器进行可视化。还提供了用于在体内特别是通过共聚焦荧光内窥镜可视化细胞的内部熄灭探针,以及内部熄灭探针与共聚焦荧光内窥镜结合使用,通过细胞内部化和解熄灭探针来可视化细胞。在一个特定实施例中,这些细胞是激活的中性粒细胞,例如在受试者的肺内。
