This gets stuck on the cell's surface and then reacts with a stain that is added to the sample.

这种酶可以粘附到细胞的表面然后和一种添加的样本上的染色剂反应。

This photomicrograph was obtained by scanning a beam of electrons across the sample while a detector kept track of electrons bouncing off its surface, betraying the specimen's outer shape.

这幅显微照片是通过扫描穿过样品的电子束而获得的，同时检测器对从样品表面反弹的电子进行追踪，这些电子显示了标本的外形。

Atomic force microscopy generates very high-resolution images (about 5-nanometer resolution) by “feeling” the surface of a sample with a tiny probe tip.

原子力显微镜是运用一种微小的探针去“感受”样本表面，能得到高分辨率的影像（约5纳米的分辨率）。

Curiosity drilled a hole in Mars to collect a sample of its surface, which is the first time any rover has drilled such a hole on the Red Planet.

FORBES: Curiosity Drills A Hole On Mars

Earlier this month, the Mars Curiosity rover drilled into the Martian surface, in the hopes of collecting a sample from the interior of a rock.

University of Miami pathologist Richard Cote is using Yang's principle of a lensless microscope to pioneer a way to move a microscope across sample cells located on a fixed surface.
