Research progress on preparative parameters that influnce the characteristics of PLA/PLGA/PELA microspheres prepared by double emulsion method / 国际生物医学工程杂志

At present PLA and its copolymer is a kind of most widely used biodegradable polymers to prepare microspheres because of its good biocompatibility. The double emulsion method is the most used technique for microspheres loade with water-soluble drugs, proteins and peptides. Microspheres with different particle size or release character could be used in different applications such as targeted drug delivery or long-acting drug delivery. The characters of microspheres are influenced by the preparative parameter. This article reviewed the preparative parameters that influence the character of microspheres.
