It is my view that all forms of electro-generated CS are effective in controlling infection and so on. One type may be better than another, but without proper double blind testing we will never know for sure. Test tube and petri dish limit tests can show marked difference in killing power between the processes, but does this necessarily translate in vivo. Does the bio-availability depend upon the form of the silver. Read on, mad scientist. Colloids: The definition of a colloidal system is "small 'particles' of one substance distributed more or less uniformly throughout another. This latter phase is continuous whilst the 'particles' are discontinuous. The continuous phase may be a gas, liquid, or solid whilst the discontinuous phase may also be a gas, liquid or solid. The system will be colloidal if the 'particles' are sufficiently small and that usually means less than about 1um in at least one important dimension." - Introduction to Modern Colloid Science...Hunter. Whilst colloidal silver systems, properly called silver sols or colloidal sols, approach the dimensions of true solutions and exhibit little or no difference from true solutions, they are regarded as colloidal if the size of the particle falls between 1 - 1000 nm (0.001 - 1.0 um). So you can see that being colloidal does not refer at all to the valence state of the dispersed particles, that is, the particles may be charged or not. Typically colloidal silver particles are charged, and therefore are ionic in one sense of the term, and may comprise of flocks of monatomic ions or a mixture of monatomic ions and metallic atoms. The aggregation of particles into flocks is a complex interaction of opposing forces: Van de Waals force is a long range attractive force occurring between any two particles of the same material and is present in all lyophobic sols. The electrostatic repulsion which opposes aggregation, and the attractive force which acts to bind particles together if they come into close enough contact, is explained by the DLVO theory. Obviously, the higher the charge a particle has, the more stable the colloid (higher zeta potential). But as the particle size approach those of true solutions, the solvation of the particles and Brownian motion ensure dispersion and charge has less importance in colloid stability. Ions: An ion is a charged particle. The particle may be an atom, or a molecule composed of like atoms or dissimilar atoms. In chemistry, generally ions are the smallest form of the element or compound, in colloid chemistry ions are usually much larger. When a silver colloid forms, the colloid particles are comprised of what is emanating from the electrodes, perhaps influenced by the pH and purity of the water. So by and large, if single atomic ions leave the anode, the colloidal aggregates are composed of atomic ions, and would, I should think, form crystalline structures. If what emanates from the electrode is small metallic particles, then the aggregates would be uncharged metallic crystals, and if a mixture of charged and uncharged... When the particles are sputtered by electric arc, not only are silver ions and metallic particles formed, but the atmosphere in which the arc is formed may also undergo chemical change, the products of which may go into solution or react with the silver particles forming silver compounds. (this is not a value judgement). These aggregates are not held together in the conventional covalent or ionic bonds, but are rather loosely bound by van der Waals attraction, indeed I believe that silver will not conduct electricity until at least 35 atoms have joined together. Whether any of this matters inside the body is another matter! Colloids do not enter the system with out help, they cannot simply cross the cell membrane or penetrate the tight junctions between cells without being transported by some chelating agent. This implies that silver must be broken into atomic ions in order for chelation to take place, and the loose attraction of small CS aggregates probably promotes this process. So perhaps when all is said and done colloidal silver enters the body as atomic silver ions no matter what the specific contents of the bottle.
