Mesoprocess is a trademarked name of an advanced proprietary process developed by the scientists at the Colloidal Science Laboratory, Inc.

The mesoprocess is a continuous process used to produce metal nanoparticles of virtually any metal, including those from the platinum group. Metal colloids produced using this unique new method are called mesocolloids.

Colloids produced using the mesoprocess start out as high purity metal having a purity of 0.9999, commonly called four nines purity. While the details of the transformation process that converts solid metal to sub-nanometer particles are proprietary (a trade secret) the concept is simple. The metal is first rendered into a form consisting of its individual atoms. The individual atoms are then coalesced into particles consisting of nine or more atoms each. In the case of silver this produces particles that are 0.65 nm in diameter, or 2.3 times the diameter of a single atom. These metal particles are then uniformly dispersed in pure pharmaceutical grade deionized water to produce a nanoparticle suspension. The particles remain suspended in the water indefinitely due to a small negative electric charge imparted to each particle called its zeta potential. The zeta potential produces a mutual repulsion of the particles which keeps the particles uniformly dispersed in the water indefinitely.

There are no chemicals, protein binders or other additives used in the mesocolloids, only pure metal and pure water.

The development of the mesoprocess from inception through design and development of the specialized equipment needed to implement the process consumed over 15,000 hours of effort over a period of five years by the scientists at the Colloidal Science Laboratory, Inc.
