Abstract
The present invention includes systems, methods and compositions for the encapsulation of particles. In one form, the system comprises one or more particles, a rotatable reaction chamber in a plasma enhanced chemical reactor to accept one or more particles, and at least one carbonaceous compound to be used in the rotatable reaction chamber, wherein the carbonaceous compound is polymerized onto a surface of one or more particles forming a polymer film encapsulating one or more particles. Using systems, methods, and compositions of the present invention, any particle encapsulated with a degradable or nondegradable polymer film may be introduced and/or released into an environment. The polymer film as well as introduction of encapsulated particles and release therefrom into an environment are controlled by the present invention.
