Atomic force microscopy (AFM) is a widely used technique in all fields of science and engineering, due to its ability to measure surfaces with sub-nanometre resolution and high accuracy. The main disadvantage of the scanning tunnelling microscopy (STM) is that it can only be used on conductive...
Atomic Force Microscopy (AFM) traces the topography of samples with extremely high - up to atomic - resolution by recording the interaction forces between the surface and a sharp tip mounted on a cantilever. In addition to topographic high-resolution inf

发布时间:2019-10-30 16:44 原文链接: 原子力显微镜(AtomicForceMicroscopy,简称AFM) 原子力显微镜的工作原理就是将探针装在一弹性微悬臂的一端,微悬臂的另一端固定,当探针在样品表面扫描时,探针与样品表面原子间的排斥力会使得微悬臂轻微变形,这样,微悬臂的轻微变形就可以作为探针和样品间排斥力的直接量度。一束...
The Atomic Force Microscope (AFM)What are its Uses in Microscopy today? Advantages and DisadvantagesAn atomic force microscope is a type of high resolution scanning probe microscope that has a resolution that you can measure in fractions of a nanometer....
原子力显微镜 Atomic Force Microscopy (AFM) 原子力显微镜(AFM)是扫描探针显微镜(SPM)的一种方法,它是一种测量局部性质(如高度、摩擦力和磁性)的综合技术。AFM由悬臂末端的尖端作为探针组成,探针通常为3-6µm高的棱锥体,端部半径为15-40nm,用于测量探针与样品表面之间的作用力。 原子力显微镜利用光学杠杆测量...
In our section on AFM theory, the basic principles and components of atomic force microscopy are explained. We show how AFM is based on the cantilever/tip assembly that interacts with the sample, how calibration works, and explain the principle of feedba
Protein translocation across cellular membranes is an essential and nano-scale dynamic process. Here, the authors visualize protein translocation via the SecYEG-SecA complex in a nanodisc by high-speed atomic force microscopy (HS-AFM), shedding light on the structural changes of SecA in this proc...
AFM 力谱是指单点测量,其中悬臂接近并“刺入”样品,然后缩回。在此过程中,测量悬臂偏转与压电运动,最终将其转换为力与尖端-样品分离的测量,从而提供有关样品的机械信息。这种转换需要校准弹簧常数和偏转灵敏度。 悬臂偏转与Z压电的模型力曲线如下: 力曲线可分为不同的部分,其中A-C(黑线)是指尖端接近表面时的运...
什么是原子力显微镜(Atomic Force Microscopy)? 原子力显微镜(AFM)于1985年由Binnig、Quate和Gerber首次展示。从那时起,这种高分辨率的非光学成像技术已经成为表面分析的有力工具。 AFM是一种精确和非破坏性的方法,可以获得各种测量,包括样品表面的地形、电、磁、化学、光学和机械测量。AFM可以在空气、液体或超高真空...
