-7. (canceled)
A method of making a sub micronic particle stabilizing solution, which comprises the steps of
- (a) obtaining fresh biological tissue;
- (b) macerating the biological tissue in water to form a suspension containing the extracts of the biological tissue;
- (c) removing from the suspension suspended particles greater than one micron to obtain a clear concentrated extract;
- (d) diluting the concentrated extract with deionized water in a ratio ranging from the original to 1 to 10 dilution;
- (e) adjusting the temperature to 25 degrees Celsius;
- (f) adjusting the pH of the diluted extract to between 5.5 to 7.5 pH;
- and
- (g) measuring the open circuit potential to ensure that that potential lies within the range of +0.1 to +0.2 volt;
- and
- (h) measuring the total organic carbon content to ensure that the content is at least 18,000 parts per million in solution.

A method of making a sub micronic particle stabilizing solution in which the removal of suspended particles is achieved by filtering the suspension through a sub micronic filter element.
A method of stabilizing sub micronic particles which comprises the steps of
- (a) dispersing sub micronic particles in deionized water to form a dispersion in which the concentration of the particles is in the range of 150 to 60000 ppm;
- (b) adding the dispersion to the stabilizing solution of claim 1 to obtain a resultant in which the concentration of the particles ranges from 5 to 300 ppm;
- (c) mixing the resultant for a period of 30 minutes to three hours to obtain a suspension of stabilized solid sub micronic particles.
A method of stabilizing sub micronic metal particles, during their synthesis, which comprises the steps of
- dispersing salt of the metal in deionized water to form a solution;
- adding the formed solution to the stabilizing solution in accordance with claim 1, to obtain a resultant in which the concentration of the metal is in the range from 5 to 300 ppm and the effective dilution of the stabilizing solution is in the range of 1:1 to 1:10;
- adding a reducing agent to the resultant;
- and
- mixing the resultant for a period of 30 minutes to three hours to obtain a suspension of stabilized solid submicronic particles.
