Abstract

A cold plasma device is suitable for treating a region of a biological surface. Some embodiments of the device include a cold plasma generator with an electrode and a dielectric barrier. The dielectric barrier includes a first side that faces the electrode and a second side that faces away from the electrode. An actuator and a controller cooperate to selectively position the cold plasma generator relative to the biological surface. Some embodiments include 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.
