A system and method for collecting, mixing and/or extracting particles from within an article, e.g., by size or density, including the steps of applying a sound wave to the article, whereby the sound wave disperses particles throughout the article, and optionally transporting and/or collecting the particles from the article. This system and method is useful for applications that require noninvasive methods to effect the movement of particles within articles that may contain materials such as solids, fluids, and/or gases.
