Atomic Force Microscopy (AFM) operated in the frequency modulation (FM) mode in ultra–high vacuum conditions (commonly known as Non–Contact AFM, NCAFM) has become an essential tool for nanoscience [1,2]. NCAFM allows us to explore and manipulate matter at the atomic scale through the inte...
Unlike expensive EM, the visible pAFM system can be simply implemented by adding an optical excitation sub-system to a commercial atomic force microscope. Light: Science & Applications (2017) 6, e17080; doi:10.1038/lsa.2017.80; published online 3 November 2017 Keywords: Arabidopsis imaging; gold...
created an experimental setup consisting of a microfluidic chamber mounted on a combined AFM and confocal microscope (AFM-CLSM) to study mouse submandibular salivary gland sections with force-spectroscopy [93]. This setup allowed for a constant media flow to study real-time mechanical changes in ...
DIY AFM (Atomic Force Microscope) / 自己動手做原子力顯微鏡: I am pleased to share with you that the DIY AFM is reported by the latest Nature Nanotechnology 10, 480 (2015) that the DIY AFM is assembled by junior high school student and successfully measu
During the process, the deflection of the cantilever and the movement of the piezo tube are recorded to produce so-called force curves. Figure 1B shows a schematic diagram of a force curve obtained during the approach-retract cycles. A force curve contains two com- ponents: an approach ...

The atomic force microscope (AFM) is a form of scanning probe microscopy that achieves sub-nanometer imaging resolution, far exceeding the optical diffraction limit, by mechanically feeling the surface of a sample with a highly sensitive probe. ...
