Methods and apparatuses for stretching polymers
TL;DR: In this paper, the authors provide structures and methods that allow polymers of any length, including nucleic acids containing entire genomes, to be stretched into a long, linear conformation for further analysis.
Journal ArticleDOI
Creation of a three-dimensional optical chain for controllable particle delivery
TL;DR: This work proposes a design for producing a conveyable quasi-periodic optical chain that can stably trap and deliver multiple individual particles in three dimensions at different planes near the focus.
Journal ArticleDOI
Fibrin mechanical properties and their structural origins
TL;DR: Fibrin deformability is not only an essential part of the biomechanics of hemostasis and thrombosis, but also a rapidly developing field of bioengineering that uses fibrin as a versatile biomaterial with exceptional and tunable biochemical and mechanical properties.
Journal ArticleDOI
The ClpXP protease unfolds substrates using a constant rate of pulling but different gears.

TL;DR: Single-molecule analyses reveal that phosphate release is the force-generating step in the ATP-hydrolysis cycle and that ClpXP translocates substrate polypeptides in bursts resulting from highly coordinated conformational changes in two to four ATPase subunits.
Journal ArticleDOI
Direct measurements of base stacking interactions in DNA by single-molecule atomic-force spectroscopy.
TL;DR: It is suggested that these transitions, which occur at approximately 23 pN and approximately 113 pN, directly capture, for the first time, the mechanical signature of base-stacking interactions among adenines in DNA, in the absence of base pairing.

Direct mechanical measurements of the elasticity of single DNA molecules by using magnetic beads
TL;DR: Deviations from the force curves predicted by the freely jointed chain model suggest that DNA has significant local curvature in solution, and the effect of bend-inducing cis-diamminedichloroplatinum (II) was large and supports the hypothesis of natural curvatures in DNA.
Journal ArticleDOI
Application of the method of phage T4 DNA ligase-catalyzed ring-closure to the study of DNA structure. II. NaCl-dependence of DNA flexibility and helical repeat.
TL;DR: It is demonstrated that it is possible to determine the molar cyclization factor jM from single ligation reactions in which both circular and linear dimer DNA species are formed concurrently from linear monomers.

Polymer conformational statistics. III. Modified Gaussian models of stiff chains
M. Fixman,J. Kovac +1 more
TL;DR: In this article, a modified Gaussian probability for intrachain distances was used to account for polymer chain stiffness or excluded volume effects in non-Newtonian viscosity theory.
