Development of ionic liquids for bioscience

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.
