英文摘要：

Knowledge of biological systems critically depends on the ability to sort and separate biomolecules efficiently and accurately. The development of the nanofilter and its applications to separation of biomolecules have attracted much research attention, and the nanofilter has become one of the hot spots in gel-free separation of biomolecules. The technique and theoretical models are discussed to reveal the progress that has been made in biomolecule separation using nanofilters. Computer simulation of the nanofilter is also discussed. In recent years, the advantages of nanofilters compared with traditional separation methods for biomolecules have become increasingly apparent. Moreover, with the progress of nanotechnology the nanofilter will have commercial applications.
