Supercritical fluid synthesis (SFS) is a versatile and innovative technique used to create nanomaterials with unique properties. This method employs supercritical fluids—substances at a temperature and pressure above their critical point—acting both as solvents and reaction media. The most commonly used supercritical fluid for nanotechnology applications is supercritical carbon dioxide (scCO2) due to its non-toxic, non-flammable, and relatively low critical parameters.
