What is Rapid Expansion of Supercritical Solutions (RESS)?
The Rapid Expansion of Supercritical Solutions (RESS) is a process used to create nanoparticles by rapidly expanding a supercritical fluid containing a dissolved substance through a nozzle. This sudden expansion reduces the solvent power of the fluid, causing the solute to precipitate as nanoparticles. The technique leverages the unique properties of supercritical fluids, which exhibit both gas-like and liquid-like characteristics, to achieve fine control over particle size and morphology.
