This work presents an approach to build a high-performance, low-viscous and replaceable separation matrix, semi-crosslinked polyacrylamide （semi-CPA） capillary gel electrophoresis. Non- denatured basic proteins, such as lysozyme, cytochrome C, ribonuclease A and trypsin were separa- ted. The impacts of monomer and cross-linker concentrations on protein separation were studied, and the ability of dynamic capillary inner wall coating was demonstrated. The UV absorption interfer- ence by semi-CPA gel matrix was successfully overcome by a partial filling technique, which results in sensitivity 20 times higher than other protein separation method. The excellent separation ability, reproducibility and dynamic coating ability made semi-CPA an ideal separation media in both capillar- y electrophoresis and microfluidic chip separation scheme.

Biomass pretreatment process is required before the conversion of biomass into chemical intermediates or fermentable sugars. Traditional pretreatment methods using acid or alkaline solvents are effective in delignification and hydrolysis but with corrosion and pollution to the environment. Therefore, scientists pay particular attention to develop new pretreatment methods for biomass utilization. Ionic liquids(ILs) with excellent properties are widely used in biomass pretreatment.1, 2 In ILs pretreatment, the delignification and disruption of cellulose crystalline could well be achieved.3 While, more efficient ILs methods are still needed to improve the biomass pretreatment. In this work, highly efficient pretreatment of biomass was investigated by different kinds of ILs. For example, efficient delignification of cornstalk was obtained in biodegradable IL choline acetate, high dissolution of chitin was achieved in 1-ethyl-3-methylimidazolium acetate and economic pretreatment of cornstalk was accomplished by ILs + additives or two-step ILs methods. Those methods indicated that ILs could be promising solvents for biomass pretreatment in the future.
