In this paper, we describe an original, affordable, and available device for performing collagen crosslinking. This is carried out in a safe and reproducible way by means of a simple modification to an affordable ultraviolet A lamp and by preparing riboflavin 0.1% solution inhouse.

Structure formation and constant reorganization of the actin cytoskeleton are key requirements for the function of living cells. Here we show that a minimal reconstituted system consisting of actin filaments, crosslinking molecules and molecular-motor filaments exhibits a generic mechanism of structure formation, characterized by a broad distribution of cluster sizes. We demonstrate that the gr...

The effects of the carbon nanotube (CNT) length and material structure on mechanical properties free-standing thin CNT films with continuous networks bundles nanotubes covalent cross-links are studied in large-scale simulations. simulations performed based a dynamic mesoscopic model that accounts for stretching bending CNTs, van der Waals interaction between nanotubes, inter-tube cross-links. I...

We investigate the behavior of the shear viscosity eta(p) and the mass-dependent diffusion coefficient D(m,p) in the context of a simple model that, as the cross link density p is increased, undergoes a continuous transition from a fluid to a gel. The shear viscosity diverges at the gel point according to eta(p) approximately (p(c)-p)(-s) with s approximately 0.65. The diffusion constant shows ...

We report on a novel facile method towards a synthesis of cyclic assembled gold nanoparticles (AuNPs) by mixing each of the DNA-monoconjugated AuNPs, i.e., "DNA building blocks" for cyclic assembly, and UV-induced interstrand crosslinking. By using our designed template DNA for cyclic assembly which possesses complementary sequences for cyclic assembly of the AuNPs, we demonstrated the formatio...

Three homochiral cadmium camphorates have been prepared through temperature-dependent synthesis; they form 3D homochiral networks without the crosslinking or pillaring functions of auxiliary neutral bipyridines and exhibit various degrees of charge separation associated with the degree of hydration and controllable by temperature.

Kinesin-5s help assemble the bipolar spindle by crosslinking and sliding apart antiparallel microtubules. A recent study has uncovered a novel pathway for the phospho-regulation of these motors.
