What Is Atomic Force Microscopy? Atomic force microscopy (AFM) is a powerful technique that enables surface ultrastructure visualization at molecular resolution. 1 Besides three-dimensional (3D) ...

Anyone who has ever taken the time to critically examine a walnut knows that a two-dimensional photograph fails in many respects to truly convey the unique features--the nicks, crannies, valleys, and ...

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force microscope, then we look at a real AFM (an nGauge AFM from ICSPI) and do a few ...

At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules. DNA is a molecule found in just about every living cell. Because ...

Atomic force microscopy (AFM) is a way to investigate the surface features of some materials. It works by “feeling” or “touching” the surface with an extremely small probe. This provides a ...

AFAM operates by exciting the sample with ultrasonic waves while simultaneously probing the surface with an AFM tip. The ultrasonic waves cause the sample to vibrate, and the AFM tip detects these ...

Doing it yourself may not get you the most precise lab equipment in the world, but it gets you a hands-on appreciation of the techniques that just can’t be beat. Today’s example of this adage: [Stoppi ...

Polymer materials play an increasingly important role in a variety of industrial applications, thanks to their distinct physical and chemical properties. Among their key mechanical characteristics, ...

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University report in Small Methods the 3D imaging of a suspended nanostructure. The technique used is an extension of atomic force ...
