Dynamic force spectroscopy of DNA hairpins. II. Irreversibility and dissipation [PDF]

, 2009
We investigate irreversibility and dissipation in single molecules that cooperatively fold/unfold in a two state manner under the action of mechanical force.

Using Single-Molecule Chemo-Mechanical Unfolding to Simultaneously Probe Multiple Structural Parameters in Protein Folding

Methods and Protocols, 2019
While single-molecule force spectroscopy has greatly advanced the study of protein folding, there are limitations to what can be learned from studying the effect of force alone.

Probing ion transport at the nanoscale: Time-domain electrostatic force spectroscopy on glassy electrolytes

, 2004
We have carried out time--domain electrostatic force spectroscopy on two different ion conducting glasses using an atomic force microscope. We compare the electrostatic force spectroscopic data obtained at different temperatures with macroscopic ...

OPTICAL PROPERTIES OF CdS–Ag2S QUANTUM DOT SYSTEM

Конденсированные среды и межфазные границы, 2017
The paper presents the results of a study of systems with quantum dots of two types: CdS and Ag2S, which have different types of crystal lattices. CdS quantum dots were synthesized in the gelatin matrix by means of the sol-gel method.

Single Chain Force Spectroscopy: Sequence Dependence

, 2001
We study the elastic properties of a single A/B copolymer chain with a specific sequence. We predict a rich structure in the force extension relations which can be addressed to the sequence.

Interaction imaging with amplitude-dependence force spectroscopy

, 2013
Knowledge of surface forces is the key to understanding a large number of processes in fields ranging from physics to material science and biology. The most common method to study surfaces is dynamic atomic force microscopy (AFM).

Probing three-dimensional surface force fields with atomic resolution: Measurement strategies, limitations, and artifact reduction

Beilstein Journal of Nanotechnology, 2012
Noncontact atomic force microscopy (NC-AFM) is being increasingly used to measure the interaction force between an atomically sharp probe tip and surfaces of interest, as a function of the three spatial dimensions, with picometer and piconewton accuracy.
