Journal ArticleDOI
Frictional adhesion: A new angle on gecko attachment.
TL;DR: The frictional adhesion model provides an explanation for the very low detachment forces observed in climbing geckos that does not depend on toe peeling.
Journal ArticleDOI
Effective elastic modulus of isolated gecko setal arrays
TL;DR: The hypothesis that Eeff of gecko setae falls within Dahlquist's criterion for tack is tested, the validity of a model of setae as cantilever beams is evaluated, and highly linear forces of deformation under all compression conditions support the cantilevers model.
Journal ArticleDOI
A high-speed magnetic tweezer beyond 10,000 frames per second
TL;DR: The ability of the high-speed magnetic tweezer to resolve particle position to within 1 Å at 100 Hz, and to measure the extension of a 1566 bp DNA with 1 nm precision at 100Hz in the presence of thermal noise is demonstrated.
Journal ArticleDOI
Activities of gyrase and topoisomerase IV on positively supercoiled DNA.
Rachel E. Ashley,Andrew Dittmore,Sylvia A. McPherson,Charles L. Turnbough,Keir C. Neuman,Neil Osheroff +5 more
TL;DR: Gyrase is better suited than topoisomerase IV to safely remove positive supercoils that accumulate ahead of replication forks, and it is suggested that the wrapping mechanism of gyrase may have evolved to promote rapid removal of positivesupercoils, rather than induction of negative super coils.
Journal ArticleDOI
Polydopamine encapsulation of fluorescent nanodiamonds for biomedical applications.
Hak-Sung Jung,Kyung-Jin Cho,Yeonee Seol,Yasuharu Takagi,Andrew Dittmore,Paul A. Roche,Keir C. Neuman +6 more
TL;DR: A robust polydopamine encapsulation and functionalization strategy presents a facile route to develop FNDs as multifunctional labels, drug delivery vehicles, and targeting agents for biomedical applications.
