Synthesis of nanoparticle in liquid, semi-solid media and in cells and tissues using cold plasma technology

A method, comprising:

• applying a substance to an area of interest, wherein the area of interest comprises a biofilm, wherein the substance is a solution that contains metal ions, wherein the metal ions of the substance diffuse into the area of interest, and wherein the metal ions impregnate cells within the biofilm;
• subsequent to diffusion of the metal ions into the area of interest and impregnation of the cells of the biofilm with the metal ions, applying cold plasma to the area of interest;
• and
• with at least a portion of the applied cold plasma within the area of interest, synthesizing nanoparticles inside cells within the biofilm, wherein the nanoparticles synthesized are metallic in nature, and wherein the nanoparticles are synthesized when the cold plasma within the area of interest reduces the metal ions impregnated within cells within the biofilm to metal atoms such that the cells contain the metal atoms,
• wherein following reduction of the metal ions impregnated within the cells within the biofilm to metal atoms such that the cells contain the metal atoms, the biofilm is incorporated into a second, targeted biofilm that is different from the biofilm.
