TLDR
The basic principles, advantages and limitations of the most common AFM bioimaging modes are reviewed, including the popular contact and dynamic modes, as well as recently developed modes such as multiparametric, molecular recognition, multifrequency and high-speed imaging.
Abstract
Atomic force microscopy (AFM) is a powerful, multifunctional imaging platform that allows biological samples, from single molecules to living cells, to be visualized and manipulated. Soon after the instrument was invented, it was recognized that in order to maximize the opportunities of AFM imaging in biology, various technological developments would be required to address certain limitations of the method. This has led to the creation of a range of new imaging modes, which continue to push the capabilities of the technique today. Here, we review the basic principles, advantages and limitations of the most common AFM bioimaging modes, including the popular contact and dynamic modes, as well as recently developed modes such as multiparametric, molecular recognition, multifrequency and high-speed imaging. For each of these modes, we discuss recent experiments that highlight their unique capabilities.

Direct Observation and Manipulation of Supramolecular Polymerization by High-Speed Atomic Force Microscopy

TL;DR: High-speed atomic-force microscopy was applied, which has extraordinary spatiotemporal resolution, to capture dynamic events occurring during synthetic molecular self-assembly, and permitted the visualization of unique dynamic behavior, such as seeded growth and self-repair in real time.

Atomic force microscope

TL;DR: The atomic force microscope as mentioned in this paper is a combination of the principles of the scanning tunneling microscope and the stylus profilometer, which was proposed as a method to measure forces as small as 10-18 N. As one application for this concept, they introduce a new type of microscope capable of investigating surfaces of insulators on an atomic scale.

Force measurements with the atomic force microscope: Technique, interpretation and applications

TL;DR: The atomic force microscope (AFM) is not only used to image the topography of solid surfaces at high resolution but also to measure force-versus-distance curves as discussed by the authors, which provide valuable information on local material properties such as elasticity, hardness, Hamaker constant, adhesion and surface charge densities.

Frequency modulation detection using high‐Q cantilevers for enhanced force microscope sensitivity

TL;DR: In this article, a frequency modulation (FM) technique has been demonstrated which enhances the sensitivity of attractive mode force microscopy by an order of magnitude or more, which is made possible by operating in a moderate vacuum (<10−3 Torr).
