TL;DR: The role of chemical sputtering corresponding to the synergism between ion bombardment of a surface with the simultaneous reaction of active species such as O, O2 or H is demonstrated and it is shown that plasma processes can be efficient against different micro-organisms, bacteria and fungi, pyrogens, model proteins and prions.

TL;DR: Atomic force microscopy (AFM) pull-off experiments performed in air with hydrophilic tips and samples show that stretched nanoscopic water bridges are in mechanical equilibrium with the external pull-offs force acting at the contact but not in thermodynamic equilibrium withThe experimental findings are explained by a theoretical model that considers constant water volume and decrease of watermeniscus curvature during meniscus stretching.

TL;DR: Force–displacement curves measured in indentation experiments performed with silicon nitride AFM probes with pyramidal tips on live cells agree well with the theoretical prediction and are used to determine the cell elasticity modulus and indenter-cell work of adhesion.

TL;DR: The surfaces are suitable for controlling the patterning of stem cells and provide a platform for the assessment of the way how different cell arrangements and culture conditions influence cell interactions and cell developmental processes.

TL;DR: In this article, the effect of UV light irradiation on the hydrophilicity of amorphous titanium dioxide thin films obtained by radio frequency magnetron sputtering deposition was studied in relation with film thickness.
