We describe a wide-field preclinical imaging system optimized for time-gated detection of quantum dot fluorescence emission. As compared to continuous wave measurements, image contrast was substantially improved by suppression of short-lifetime background autofluorescence. Real-time (8 frames/s) biological imaging of subcutaneous quantum dot injections is demonstrated simultaneously in multiple living mice.
我们描述了一种优化的宽场临床前成像系统,用于门控检测量子点荧光发射。与连续波测量相比,通过抑制短寿命背景荧光的本底,显著提高了图像对比度。同时对多只活体小鼠进行了实时(8 帧/秒)的皮下量子点注射的生物成像。
