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.

Predicting Metastasis with a Novel Biophysical Cell-Adhesion Force Technique

TL;DR: A novel and inexpensive bead-pipette assay is tested to investigate the adhesion forces of non-metastatic NIH3T3 cells and mutated RasV12 cells, a metastatic model cell line and showed potential as a classifier for determining metastasizing cells from non-Metastatic cells.
Journal ArticleDOI

Long-range hydrodynamic forces in liquid FM-AFM.

TL;DR: It is pointed out that the evolution of k int at short and long distance arises from unsteady hydrodynamic forces on the cantilever, and β int is small at long distance and diverges at short probe-surface distance, as predicted by the classical Reynolds sphere model.

Practical Guide to Single-Protein AFM Nanomechanical Spectroscopy Mapping: Insights and Pitfalls As Unraveled by All-Atom MD Simulations on Immunoglobulin G.

TL;DR: In this paper, the authors performed all-atom molecular dynamics simulations of the indentation process on a single immunoglobulin G (IgG) adsorbed on a graphene slab.

Principles and Applications of Liquid‐Environment Atomic Force Microscopy

TL;DR: A review on the development history of liquid-environment atomic force microscopy (LE•AFM) can be found in this article , with an emphasis on challenges posed by liquid environments and corresponding solutions.
Journal ArticleDOI

The effects of measurement parameters on the cancerous cell nucleus characterisation by atomic force microscopy in vitro

TL;DR: The results revealed that the Young's moduli of A549 cells increased with the larger indentation force, higher indentation speed, less retraction time, deeper Z length and lower purity percentage of serum, and decreased with the increasing dwell 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.

Lipid Rafts As a Membrane-Organizing Principle

TL;DR: The evidence for how this principle combines the potential for sphingolipid-cholesterol self-assembly with protein specificity to selectively focus membrane bioactivity is reviewed.

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).
