Abstract:
1. A method for forming a nano-bubble, the method comprising: taking an inorganic particle as a nucleus and performing a polymer coating process to coat (poly(isobutylene-alt-maleic anhydride)-graft-dodecylamine) on the nucleus to form an organic/inorganic composite particle, wherein the inorganic particle is one particle selected from the group consisting of the following: gold, silver, and iron; dripping aqua regia into a solution containing said organic/inorganic composite particle to dissolve said nucleus; using a 100 KDa filter tube to replace aqua regia with sodium borate buffer (SBB), and then replacing the SBB with deionized water to remove the dissolved nucleus of the organic/inorganic composite particle, and forming an impregnated nano-particle impregnated with the deionized water; performing a freeze-drying process on the impregnated nano-particle to form a hollow nano-particle; and placing the hollow nano-particle into the deionized water to form the nano-bubble in the deionized water; wherein the nano-bubble has a particle diameter of 30-100 nm.
