The value of the nanogold in the vials is a fraction of a penny. The gold is so small we need very little of it to use as a sensor. This is one of the advantages of using nanoscale materials. The Main Electrolytes in Body Fluid Na+ ClMg ++ Ca++ K+ Na+ Sodium Ion Chloride Ion Magnesium Ion Calcium Ion Potassium Ion Cl- K+ Each ion has its own rules, and body movement is a result of the function of these ions.
