     When polyelectrolyte multilayers were assembled on different size of ZnCO_3 microparticles, different size hollow microcapsules can be obtained after ZnCO_3 microparticles were dissolved by HC1. The size of hollow microcapsules were determined by the size of the ZnCO_3 microparticles, so the hollow microcapsules obtained were also size-controlled.

Methods Microcapsules for islet transplantation were made of alginate and BaCl 2 by the method of one step solidification. 2 000 hollow microcapsules were suspended in normal saline at 37 ℃ for 2 months; another 2 000 hollow microcapsules were put into normal saline at 37 ℃ and shaken at 150 r/min for 1 hour, the ratio of the broken microcapsules was counted and the changes of their shape were observed. 5 000 microcapsules per rat were injected into the peritoneal cavity of 12 Wistar rats, four rats were killed at 2, 6, 10 weeks respectively and their peritoneal cavities were washed out with saline, the ratio of the broken microcapsules was counted and the changes of their shape were observed. Results The ratio of the broken microcapsules were 10% and 18%. At 2nd week about 3 000 microcapsules per rat were washed out, and they were intact and round without fibrosis. At 6-10 weeks, only 1 000-1 500 microcapsules were washed from one rat, 10%-15% of them were deformed or broken with remarkable fibrosis. Conclusions The alginate-BaCl 2 microcapsules made by the method of one step solidification have good solidity and biocompatibility.
