Exposure of poly(DL-lactic acid) (P DL LA), and related polymers, to supercritical CO 2 (scCO 2 ) at or below, physiological temperatures leads to very effective plasticization and liquefying of the polymers. The phenomenon arises from the high solubility and interaction of the scCO 2 in the polymer
Three micronization techniques, based on the use of supercritical carbon dioxide, were investigated to produce microspheres of a natural biocompatible polysaccharide. Particles smaller than 20 ยตm were obtained by means of the rapid expansion of a supercritical solution method (RESS), both with and w
