Journal ArticleDOI
Switchable Friction of Stimulus-Responsive Hydrogels†
TL;DR: The authors' measurements indicate that gels in a collapsed conformation exhibit significantly more friction than swollen gels (below the LCST) at low shear rates, and it is shown that the changes in friction, triggered by an external stimulus, are reversible.
Journal ArticleDOI
"Smart" DNA interfaces.
TL;DR: This review focuses on surface-grafted DNA, and its use as a molecular building block that exploits its unique properties as a directional (poly)anion that exhibits molecular recognition.
Journal ArticleDOI
In situ friction measurement on murine cartilage by atomic force microscopy.
Jeffrey M. Coles,Jason J. Blum,Gregory D. Jay,Eric M. Darling,Farshid Guilak,Stefan Zauscher +5 more
TL;DR: Interfacial shear was found to be the principal mechanism of friction generation, with little to no friction resulting from plowing forces, collision forces, or energy losses due to normal deformation in murine cartilage.
Journal ArticleDOI
Understanding the elasticity of fibronectin fibrils: unfolding strengths of FN-III and GFP domains measured by single molecule force spectroscopy.
TL;DR: The results thus favor an alternative model, which invokes a conformational change from a compact to an extended conformation, as the basis for FN fibril elasticity.
Journal ArticleDOI
Versatile synthesis and micropatterning of nonfouling polymer brushes on the wafer scale

TL;DR: POEGMA polymer brushes synthesized by surface-initiated atom transfer radical polymerization can be patterned directly by photolithography, plasma ashing, and reactive ion etching to create patterns at the micro- and nanoscale over large areas with high throughput and repeatability, while preserving the protein and cell resistance of the POEGMA brush.
