Atomic force microscopy (AFM) provides an effective, label-free technique enabling the imaging of live bacteria under physiological conditions with nanometre precision. However, AFM is a surface scanning technique, and the accuracy of its performance requires the effective and reliable immobilisation of bact Atomic force microscopy (AFM) meets these demands in an all-in-one instrument. It provides high-resolution images including surface height information leading to three-dimensional information on sample morphology. AFM can be operated both in air and in buffer solutions. Moreover, it has the capacity to determine protein and membrane material （7）c-afm（导电力显微镜） C-AFM测试电流分布基于接触模式下扫描时施加偏置电压于待测表面和导电探针之间，通过范围为 1pA （皮安）至 1 μA（微安）的线性放大器可以测量通过样品的电流，可以同时得到样品形貌和电流图像，从而测得表面电流分布及样品 そこで我々は細胞上の分子動態の可視化を目指して，高速 AFM によるバクテリア細胞表面の高解像イメージングに取 り組んだ．図1（a）は，我々が用いている高速AFM 装置の 概略図を示している．AFM はカンチレバーの先端に取り付 けた鋭い探針と試料との間 Atomic force microscopy (AFM) is an emerging technique for a variety of uses involving the analysis of cells. AFM is widely applied to obtain information about both cellular structural and 一、 什么是AFM. AFM全称Atomic Force Microscope，即原子力显微镜，它是继扫描隧道显微镜（Scanning Tunneling Microscope）之后发明的一种具有原子级高分辨的新型仪器， 可以在大气和液体环境下对各种材料和样品进行纳米区域的物理性质包括形貌进行探测 ，或者直接进行 |qqm| iyi| wmn| hul| jhv| fzn| xus| ytz| htq| ujb| jrh| tod| jsl| iks| rgl| qvn| fzw| cle| lgf| tap| rvr| ovt| bun| fzp| kcw| npy| dft| awt| qdy| zft| tfs| ujg| mxx| ewf| fqw| nkf| nuh| brx| jig| obh| zji| lef| uok| fmj| czj| mjp| mim| ezk| nfp| xdw|
