Atomistic simulations of atomic force microscopy [PDF]

, 2010
An important milestone in exploration of physical phenomena on the nanometer scale was the invention of scanning tunneling microscopy (STM) in 1982 by G. Binig and H. Rohrer. Later, using noncontact atomic force microscopy (AFM) atomic resolution has

AFM and MFM techniques for enzyme activity imaging and quantification

Biotechnology & Biotechnological Equipment, 2018
In this work, a new approach for enzyme activity monitoring is suggested. It is based on the real-time imaging, by atomic force microscopy (AFM) and magnetic force microscopy (MFM), of the degradation of a nanoparticles-loaded enzyme responsive layer ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Applications of AFM in pharmaceutical sciences

, 2015
Atomic force microscopy (AFM) is a high-resolution imaging technique that uses a small probe (tip and cantilever) to provide topographical information on surfaces in air or in liquid media.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Topography and mechanical properties of single molecules of type I collagen using atomic force microscopy

, 2005
Although the mechanical behavior of tendon and bone has been studied for decades, there is still relatively little understanding of the molecular basis for their specific properties.
