Several problems, such as recognition of surface structures of cell and observation in situ of inner structure of cell, were discussed; what s more, "shape probe" and superthin section were put forward to solve the problems.

对近年来原子力显微技术(AFM)在细胞生物学中的应用大致归纳为几个方面进行了简单介绍,还指出了细胞表面结构难于识别、细胞内部结构难以原位观察等AFM应用于细胞生物学中的难题,并提出了“形状探针”的概念以及超薄切片的思路以解决这些难题。
