=== PGSS ===
In the PGSS method (Particles from Gas Saturated Solutions) the solid material is melted and the supercritical fluid is dissolved in it.<ref>{{Cite journal|last1=Tanbirul Haque|first1=A. S. M.|last2=Chun|first2=Byung-Soo|date=2016-01-01|title=Particle formation and characterization of mackerel reaction oil by gas saturated solution process|journal=Journal of Food Science and Technology|volume=53|issue=1|pages=293–303|doi=10.1007/s13197-015-2000-3|issn=0022-1155|pmc=4711435|pmid=26787949}}</ref> However, in this case the solution is forced to expand through a nozzle, and in this way [[nanoparticle]]s are formed. The PGSS method has the advantage that because of the supercritical fluid, the melting point of the solid material is reduced. Therefore, the solid melts at a lower temperature than the normal melting temperature at ambient pressure.
