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。

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）。

This device USES a sharp point mounted on a vibrating cantilever, which scans the surface of a sample and reacts to topology and the properties of the sample to provide highly detailed images.
