[求助] 介孔硅药物释放

有谁做过介孔硅的药物释放,你们是怎么做的?我是用透析的方法,但发现有沉淀物在透析袋里,这样药物还能出来吗?

那你能说说具体步骤吗?  我现在也做药物释放  不会做...

For the pH dependent release studies, three different buffer
solutions with the same NaCl concentration (0.15 M) were
chosen: sodium acetate buffer for pH 5.0, phosphate buffer for
pH 6.5 and 7.4. DOX@M-MSN–P(NIPAM-co-MAA) was
dispersed in 2 mL of buffer, and the dispersion was transferred
into a dialysis bag (molecular weight cut off ¼ 14 000). The
dialysis bag was then kept in 200 mL of buffer and gently shaken
at 37 C. At timed intervals, 1 mL of solution was withdrawn
from the solution and analyzed by UV-vis. To keep a constant
volume, 1 mL of fresh buffer was added after each sampling. All
drug release results were averaged with three measurements,其实文献挺多的,大致就是这么个方法,你要根据具体情况而定

药物从透析袋里出来,测释放介质溶液吸收
