Acoustic Force Spectroscopy (AFS) is a single-molecule micromanipulation technique that uses sound waves to exert force on surface-tethered DNA molecules in a microfluidic chamber. Here we present a new method for multiplexed single-cell mechanical probing using acoustic force spectroscopy (AFS). Single-cell acoustic force spectroscopy (scAFS) Within a microscope-mounted chamber, an acoustic standing wave forces loose cells upward while those bound to a substrate stay put. AFS is a Lab-on-a-chip device consisting of a flow cell of two glass plates with a fluid chamber in between and a piezo element glued on top. Tuning the Music: Acoustic Force Spectroscopy (AFS) 2.0. Sigma-Aldrich offers abstracts and full-text articles by [Gerrit Sitters, Douwe Kamsma, Gregor Thalhammer, Monika Ritsch-Marte, Erwin J G Peterman, Gijs J L Wuite]. We determined that CD4 adhesion is accelerated by interleukin-7, … AFS is a recently introduced high-throughput single-molecule technique that allows studying structural and mechanochemical properties of many biomolecules in parallel. Force spectroscopy has become an indispensable tool to unravel the structural and mechanochemical properties of biomolecules. Since the approach is modular and only requires minimal modifications to the protein of interest, we anticipate it to be applicable to a wide range of proteins. In this chapter, we … Here we extend the force spectroscopy toolbox with an acoustic manipulation device that can exert forces from subpiconewtons to hundreds of piconewtons on thousands of biomolecules in parallel, with submillisecond response time and inherent stability. AFS permits high experimental throughput, because many individual molecules can be manipulated and tracked in parallel. We demonstrate the potential of scAFS by measuring adhesion forces and kinetics of CD4 + T lymphocytes (CD4) to fibronectin. A further factor in increasing the functionality is the quantification of the applied forces. Crossref, Medline, Google Scholar; Kastelowitz N, Yin H (2014). AFS permits high experimental throughput, because many individual molecules can be manipulated and tracked in parallel. By D. Kamsma, R. Creyghton, G. Sitters, G.J.L. TY - JOUR. Here we introduce single-cell acoustic force spectroscopy (scAFS), an approach that makes use of acoustic waves to exert controlled forces, up to 1 nN, to hundreds of individual cells in parallel. Methods 105, 26–33. Methods 12, 47– 50 (2015). Increasing effort into parallel single molecule force experiments has led to the development of acoustic force spectroscopy (AFS). We determined that CD4 adhesion is accelerated by interleukin-7, … The generated acoustic waves are capable of exerting forces on microspheres with … Furthermore, we explore the effect of extracellular vesicles (EVs) uptake on RBC mechanics and demonstrate that EVs uptake increases RBC deformability. It is non destructive and requires no sample preparation as the sampling waveguide can simply be pushed into a sample powder/liquid or in contact with a solid sample. Wuite and E.J.G. Stiffness and contractile prestress of living endothelial cells were determined by Acoustic Force Spectroscopy (AFS) focusing on the displacement of functionalized microspheres located at the cell-cell periphery. We demonstrate that mechanical differences induced by chemical treatments of known effect can be measured and quantified. Here we extend the force spectroscopy toolbox with an acoustic manipulation device that can exert forces from subpiconewtons to hundreds of piconewtons on thousands of biomolecules in parallel, with submillisecond response time and inherent stability. The idea is to use acoustic waves generated in a chamber to apply forces in parallel to hundreds of beads linked to individual molecules attached to the sample surface. acoustic tweezers force spectroscopy single-molecule: Abstract: Increasing effort into parallel single molecule force experiments has led to the development of acoustic force spectroscopy (AFS). Acoustic force spectroscopy (AFS or Acoustic force probe) is a recent development that uses ultrasound waves allowing high-throughput applications of single biomolecule mechanics [1,2]. These studies are performed on a large scale by biologists and within pharmaceutical companies for e.g. AU - Sitters, G. AU - Oswald, F. Most dynamic force spectroscopy experiments to date have been performed using atomic force microscopy (AFM), which requires that individual bonds be broken one at a time. Abstract. AFS™ is the first fast and easy-to-use instrument for highly parallel single-molecule manipulation and measurement. adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A AFS is a completely new and powerful technique for determining biomolecular mechanics and structure of single molecules such as DNA and proteins. Acoustic Force Spectroscopy (AFS) is a recently developed measurement tool to study single molecules making use of acoustic standing waves. Here we present a single-molecule manipulation method, acoustic force spectroscopy (AFS), that uses acoustic forces to stretch multiple molecules individually tethered between a surface and a microsphere. Single-molecule force spectroscopy has become an indispensable tool to unravel the structural and mechano-chemical properties of biomolecules. [5] In this technique, a piezo element resonantly excites planar acoustic waves over a microfluidic chip. Acoustic standing waves of MHz frequencies are able to exert forces on microspheres, which can be used for the manipulation of single bio-molecules.

Thesis advisor: Wuite, GJL; Peterman, Erwin: Publisher In addition, we anticipate that our tethering strategy will enable multiplexed protein force spectroscopy using other single-molecule methods such as acoustic and centrifugal force spectroscopy as well. Acoustic Force Spectroscopy (AFS) is used to generate multi-oscillatory forces in the range of pN-nN on particles attached to primary human umbilical vein endothelial cells (HUVEC) cultivated inside a microfluidic chip.

Force spectroscopy has become an indispensable tool to unravel the structural and mechanochemical properties of biomolecules. We demonstrate the potential of scAFS by measuring adhesion forces and kinetics of CD4+ T lymphocytes (CD4) to fibronectin. Moreover, a wide range of forces can be applied, as well as a force loading rate with range of six orders of magnitude. In most force-spectroscopy instruments only a limited number of biomolecules can be studied simultaneously, which reduces experimental throughput and limits statistics. Chembiochem 15, 923–928. Moreover, a wide range of forces can be applied, as well as a force loading rate with range of six orders of magnitude. As large numbers of individual protein-DNA complexes are tracked in parallel, AFS provides insight into the individual properties of such complexes as well as their population averages. The performance of acoustic tweezers is greatly dependent on setup design and the proper driving frequency.
