原子間力顕微鏡(Atomic Force Microscopy, AFM)はどのように機能するのでしょうか?AFMは、サンプルをナノスケールで研究するための最も用途が広くて強力な顕微鏡技術であることは間違いありません。このページでは、わかりやすい. 原子間力顕微鏡(げんしかんりょくけんびきょう、英: atomic force microscope、 AFM)[1]は、走査型プローブ顕微鏡(SPM)の一種であり、試料の表面と探針の原子間にはたらく力を検出して画像を得る顕微鏡である。 原子間力はあらゆる物質の間に働くため容易に. 高速AFMは,最高でXY方向1〜2 nm,Z方向で0.1 nmの空間分解能と30ミリ秒の時間分解能を有し,溶液中にあるタンパク質分子を動画観察することができる.高速AFMの原理や装置については文献6を,操作方法については文献7 (6~8) The AFM signals, such as sample height or cantilever deflection, are recorded on a computer during the x-y scan. They are plotted in a pseudocolor image, in which each pixel represents an x-y position on the sample, and the color represents the recorded signal. Fig. 5: Topographic image forming by AFM

These limitations are set by the x,y,z piezo components of the scanner

Dynamics are fundamental to the functions of biomolecules and can occur on a wide range of time and length scales. Here we develop and apply high-speed AFM height spectroscopy (HS-AFM-HS), a technique whereby we monito The AFM scanner is the most important component of any AFM, as its performance determines the accuracy of the imaging results. It is very important to determine if there are any scanner artifacts, such as high-order and non-linear background motions, to avoid distorting the resulting AFM image.(see Figure 2 valley height(Rt), ten point average roughness(Rz), skewness of the line(Rsk), kurtosis of the line(Rku).

But I have doubt regarding the phase image. Is this the original phase information that we are normally getting from XRD and all? What does the color.

Static mode can also be operated in constant height mode where the probe maintains a fixed height above the sample. There is no force feedback in this mode. Constant height mode is typically used in atomic resolution AFM In their recent publication High-speed AFM height spectroscopy reveals μs-dynamics of unlabeled biomolecules in Nature Communications George R.
