23 Jul Polylactic acid porous scaffold for tissue engineering and its preparation method
Abstract
The present invention discloses a preparation method of macromolecular porous scaffold material for tissue engineering, and is characterized by that said method adopts polylactic acid for tissue engineering as raw material, dissolves it in dioxane or dioxane/water mixed solvent, then makes the above-mentioned material undergo the processes of rough finish treatment at a certain temp. in a self-made mould low-temp. freeze-drying to remove solvent so as to obtain the invented three-D porous scaffold with a certain microstructure for tissue engineering. Said ivnention is simple in preparation process, and good in reproducibility.
