CNW surface functionalization and its effects on surface wettability are investigated using post-growth plasma surface treatments. The as-grown CNWs are obtained using CH4/H2 mixtures, and are then exposed to atmospheric pressure plasmas of either Ar or CF4. The results demonstrated that the functionalization occurs mainly at the CNW surfaces, edges, and defects, and has no impact on the CNW morphology; however, the chemical changes are sufficient as to render the CNW surfaces either super-hydrophilic or super-hydrophobic.

A high–efficient homogeneous air surface discharge device composed of microns-thick hollow quartz fibers is built up for inactivation applications. The inactivation efficiencies of the processing depth (the distance between the device surface and the glass slide) are systematically investigated at various pulse voltages. Measurements indicate that the surface charges and reactive species can lead to the synergistic effect on fungi cell inactivation.

Air atmospheric pressure plasma is promising method to implement the portable plasma device by removing huge carrier gas cylinder but generation of abundant amount of ozone is remaining problem. Using surface type air atmospheric pressure plasma, we investigate amounts of the ozone and other reactive species generation with variation of temperature through optical emission spectrum and tube type gas detector. Reduced version of global model is also employed to complement experimental observations.

The translation of physical technologies into medicine and biology is one of the most potent fields of science. In plasma medicine astonishing results were archived regarding its potential use in the treatment of chronic wounds. We here investigated the argon plasma – cell interactions of an atmospheric pressure argon plasma jet to human immune cells regarding their survival and proliferation.
