Development of ionic liquids for bioscience

许多新型的离子液体已经被合成，以支持几个不同的生物科学领域。本课题主要完成了以下四个方面的工作。(1)我们已经成功地合成了新型离子液体（ILs）来溶解生物质和提取有用的材料，如纤维素。(2)我们已经提出了新的方法来检测这样的纤维素转化成其他化学物质的离子液体中，以及在离子液体中提取的多糖的分子量和分子量分布的变化。然后（3）利用生物质的产物之一乙醇，在适当设计的离子液体中，在酶的辅助下进行发电。(4)还设计了离子液体作为细胞保护液，以保持细胞在空气中的生物活性。长期稳定是未来的任务。

Many novel ionic liquids have been synthesized to support several different fields of bio-science. Following four subjects have been carried out in this project. (1) We have succeeded to synthesize novel ionic liquids (ILs) to dissolve biomass and extract useful materials such as cellulose. (2) We have proposed new methods to detect material conversion of such a cellulose into other chemicals in ILs as well as changes in molecular weight and molecular weight distribution of the extracted polysacchar ides in the ILs. Then (3) ethanol, one of products from biomass, was used to generate electricity with the aid of enzymes in suitably-designed ILs. (4) Design of ILs as a protection fluid for cells has also been carried out to keep bio-activity of cells under air. Long term stability is a future task.
