Development of environmental-benign bioseparation membranes by hybridizing biodegradable porous materials and nano inorganic microcapsules

通过将生物可降解塑料的微孔膜和羟基磷灰石纳米颗粒杂交，开发了环境友好的分离膜。由研究项目负责人田中博士开发的聚（L-乳酸）深层过滤微滤膜保留了由共同研究员木村博士开发的羟基磷灰石纳米颗粒组成的微胶囊。生物可降解膜和羟基磷灰石微胶囊的混合膜吸附牛血清白蛋白，模型蛋白，在低离子强度和洗脱在升高的离子强度。

Environmentally benign separation membranes have developed by hybridizing microporous membranes of biodegradable plastics and hydroxyapatite nanoparticles. The depth filter microfiltration membranes of poly(L-lactic acid) developed by Dr. Tanaka, the head of the research project, retained the microcapsules comprised of hydroxyapatite nanoparticles developed by Dr. Kimura, the co-researcher. The hybrid membrane of the biodegradable membrane and hydroxyapatite microcapsules adsorbed bovine serum albumin, a model protein, at a low ionic strength and eluted at an elevated ionic strength.
