观察细胞等微小物体的显微镜通常都是比较大的设备,但加州大学伯克利分校的生物工程学家Luke Lee发明的显微镜却不是这样。在他的显微镜中,样本细胞被滴入到一个刻在芯片中的充满液体的管道中,在这个管道中细胞被荧光染料作上标记,然后用激光照亮。该激光光束促使染 Microscopes that look at small objects such as cells are often larger devices, but the microscope invented by Luke Lee, a bioengineer at the University of California, Berkeley, is not. In his microscope, the sample cells were dropped into a liquid-filled tube inscribed in a chip where the cells were labeled with fluorescent dyes and then laser-illuminated. The laser beam causes dye
