Abstract
The processes that form the reaction volume as plasma-dust entities during the injection of protein drug powders into RF-discharge plasma (plasma trap) have been investigated. Using albumin and acetylsalicylic acid as an example, plasma-assisted vapor deposition of sublimable organic compounds onto the surface of particles levitating in the plasma trap was studied. The geometry of the reaction volume, the dynamics of the dust particles, and the intensity of the vapor fllux can be effectively controlled using a continuous or pulse-periodic electron beam. The thickness and degree of adhesion of the deposited layer are determined by the electron beam parameters, whereas the characteristics of RF discharge have an effect only on the initial geometry and stability of the reaction volume.
