The beam-plasma source for technologies of the proteins modification

The design of the plasmachemical reactor is described. The reaction zone of the reactor is the plasma generated by injecting the continuous or intermittent electron beam into dense gaseous or vapor media containing dispersed powders of the material to be treated. The tests of the reactor showed the beams of moderate electron energy to be able to create the uniform reaction bulk, the plasma parameters (such as densities of chemically active plasma particles, the local and whole power input, temperatures of the gas and powder particles) being predictable and controllable. The reactor was used to modify native proteins. The modification was found to change the proteins properties and their bioactivity radically.
