摘要

Our data demonstrated that (1) the increase of stirring speeds will lead to reduction of PVA microsphere size; (2) Microsphere could not be when the concentration of PVA is ~13%; (3) PVA microsphere- induced cytotoxicity is related to the incorporation of SDS during process, and (5) The particle-size distribution displayed an exponential decay pattern. As particle size increased, the proportion comprising the sample decreased. Based on these preliminary data, additional experimental approaches have been designed to minimize, or eliminate the use of SDS in PVA microsphere preparation and to further improve the purification and production of PVA microspheres.
