Different Mechanisms Define the Anti-adhesive Function

Apr 22, 2002 . kininogen (HKa). HKa and particularly its His-Gly-Lys-rich domain 5 have been previously reported to exert anti-adhesive properties by binding to the extracellular matrix protein vitronectin (VN).

Molecular explanation for why talc surfaces can be both hydrophilic .

Sep 20, 2011 . Abstract: While individual water molecules adsorb strongly on a talc surface (hydrophilic behavior), a droplet of water beads up on the same surface (hydrophobic behavior). To rationalize this dichotomy, we investigate the influence of the microscopic structure of the surface and the strength of adhesive.
