Fabrication of ZnO Nanobrushes by H-CH Plasma Etching for H Sensing Applications.

Zinc oxide has widespread use in diverse applications due to its distinct properties. Many of these applications benefit from controlling the morphology on the nanoscale, where for example gas sensing is strongly enhanced for high surface-to-volume ratios. In this work the formation of novel ZnO nanobrushes by plasma etching treatment as a new approach is presented.

In vitro proinflammatory gene expression changes in human whole blood after contact with plasma-treated implant surfaces.

Background: The aim of this in vitro study was to identify changes in gene expression of proinflammatory cytokines in human whole blood after contact with titanium implant surfaces after plasma treatment.

Materials And Methods: Grade 4 titanium dental implants were conditioned with low-pressure plasma (LPP) and atmospheric-pressure plasma (APP) and submerged in human whole blood in vitro. Unconditioned implants and blood samples without implants served as control and negative control groups, respectively.
