Imaging and force measurement of LDL and HDL by AFM in air and liquid [PDF]
FEBS Open Bio, 2015 The size and biomechanical properties of lipoproteins are tightly correlated with their structures/functions. While atomic force microscopy (AFM) has been used to image lipoproteins the force measurement of these nano‐sized particles is missing.

One-Step Calibration of AFM in Liquid [PDF]
Frontiers in Physics, 2020 Nanomechanical measurements of cells and single molecules with atomic force microscopy (AFM) require accurate calibration of two parameters: the spring constant of the cantilever (k) and the inverse of the optical lever sensitivity (InvOLS).

Characterisation of tissue factor-bearing extracellular vesicles with AFM: comparison of air-tapping-mode AFM and liquid Peak Force AFM [PDF]
Journal of Extracellular Vesicles, 2013 Introduction: Extracellular vesicles (EVs) are shed from cells and carry markers of the parent cells. Vesicles derived from cancer cells reach the bloodstream and locally influence important physiological processes.

Influence of Fluid Cell Design on the Frequency Response of AFM Microcantilevers in Liquid Media
Sensors, 2008 A study of the frequency response of AFM microcantilevers in liquid media contained in a commercial fluid cell is presented. Such systems exhibit complicated dynamics which are often not well described by available theories.

A simple approximation for forces exerted on an AFM tip in liquid
The Journal of Chemical Physics, 2013 The critical quantity in understanding imaging using an atomic force microscope is the force the sample exerts on the tip. We put forward a simple one-to-one force to water density relationship, explain exactly how it occurs, and in which circumstances it holds. We argue that two wide classes of atomic force microscope (AFM) tip should lead to at least
