The mesoprocess is trademarked name of an advanced proprietary process developed by the scientists at the Colloidal Science Laboratory, Inc. This unique new process produces metal colloids consisting of mesoparticles and having a very high percentage of particles vs ions. Metal colloids produced using this unique new method are called mesocolloids.
The mesoprocess is the result of thousands of hours of research conducted over several years directed at developing a continuous process to produce metal colloids of virtually any metal, including those from the platinum group. The mesoprocess is capable of producing colloids whose particles are much smaller than those produced by other methods. The size of the particles in mesocolloids of silver are less than 2 nm in diameter (0.65 nm typical).
The most common methods used to produce colloids today include, chemical precipitation, electrochemical, and sonoelectrochemical techniques which typically produce particles whose sizes ranges from 10 nm up to several hundred nanometers. Perhaps the single most common method employed is an electrochemical process which results in a high percentage of metal ions being produced as a by-product of producing particles. Some electrochemical processes result in colloidal solutions whose metal content consists of only 1% particles, while 99% is ions.
By definition, a metal colloid is nanometer size metal particles suspending in a liquid, usually water. Therefore, it is the particles that constitute the colloid. Colloids produced by the mesoprocess have a high percentage of particles vs ions, typically 80% to 100% depending on the metal.
The term mesoparticle refers to very small particles whose size is larger than an atom and smaller than conventional small particles. Mesoparticles range in size from less than a nanometer up to 10 nanometers and typically consist of 10 - 30,000 atoms per particle. Mesoparticles may be produced by first reducing the element to its monoatomic state and then coalescing particles from the individual atoms. Atoms are typically in the range of one quarter of a nanometer.
The term mesocolloid was coined to refer to a group of metal colloids that contain mesoparticles and are produced using the mesoprocess. The first products of the group to be commercially produced are Mesosilver, Mesogold and Mesocopper. Other mesocolloid products will follow in the near future.
