Abstract: A cold plasma device generates cold plasma to treat an area of a biological surface. The device includes an array of cold plasma generators associated with a substrate. Each of the cold plasma generators has an electrode and a dielectric barrier. The dielectric barrier has a first side that faces the electrode and a second side that faces away from the electrode. A controller is operably coupled to the array of cold plasma generators and is programmed to control each of the cold plasma generators to generate a plasma dose.

Abstract: A method for pre-treating a catheter prior to using the catheter in a medical procedure, and a related apparatus, are provided. The method comprises exposing, in a plasma chamber positioned in a medical care center, and under sterile conditions, intraluminal surfaces and extraluminal surfaces of the catheter to plasma. The plasma is electromagnetically-generated adjacently to the intraluminal surfaces and extraluminal surfaces, thereby rendering, at least temporarily, the intraluminal surfaces and extraluminal surfaces of the catheter hydrophilic.

Particle based ICP analysis includes analysis of particles such as cells, beads, or laser ablation plumes, by atomizing and ionizing particles in an ICP torch followed by atomic analysis. In mass cytometry, mass tags of particles are analyzed by mass spectrometry, such as by ICP-MS. Systems and methods of the subject application include one or more of: a demountable ICP torch holder assembly, an external ignition device; an ICP load coil comprising an annular fin, particle suspension sample introduction fluidics, and ICP analyzers thereof.
