Size controlled production of biodegradable microparticles with supercritical gases

Controllable porous polymer particles generated by electrospraying

“…From a scientific viewpoint, it is possible to prepare various functionalized porous polymer particles whose applications can be expanded to the field of bionanotechnology. Currently, a number of approaches for their fabrication are employed: supercritical carbon dioxide emulsion, colloidal particles, aerosol spray techniques and controlled solvent evaporation have been developed [12][13][14][15].…”

Polymer microparticles production by supercritical assisted atomization

“…Several papers and reviews have been published on polymer processing using these techniques [15][16][17][18][19][20].…”

Pigment Red 60 micronization using supercritical fluids based techniques

“…They can be classified in two groups: supercritical antisolvent processes and supercritical assisted atomization techniques. The first group of processes uses CO 2 as the supercritical antisolvent and is represented by discontinuous processes like gas antisolvent (GAS) [2,3] and by semi-continuous processes like supercritical antisolvent (SAS) [4][5][6][7], solution enhanced dispersion by supercritical fluids (SEDS) [8,9] and aerosol solvent extraction system (ASES) [10]. The second group includes the processes that produce an enhancement of the atomization solubilizing supercritical CO 2 in molten solids (particles from gas saturated solution, PGSS) [11,12], mixing it in liquid solutions (carbon dioxide assisted nebulization with a bubble dryer, CAN-BD) [13,14] or solubilizing it in liquid solutions (supercritical assisted atomization, SAA) [15][16][17].…”
