Abstract
Methods and devices are disclosed that use focused acoustic energy to generate solid particles containing at least one compound of interest. Focused acoustic radiation serves to eject droplets containing a compound of interest dissolved in a solvent. The droplets are subjected to a condition that allows for the compound of interest to precipitate out of solution, thereby generating solid particles. The particles are typically of controlled size, composition, and/or structure. Often, particles of substantially identical size are generated.
