Prof. Yoshinobu Baba, Associate Prof. Noritada Kaji, and Assistant Prof. Takao Yasui from the Graduate School of Engineering at Nagoya University invented a new separation technology overcoming the conventional separation concept.
All the current separation technologies use a method that involves separation based on differences and interactions between physical or chemical characteristics. In general, the faster the separation speed, the worse is the separation resolution: for the better resolution, the separation speed can be slower. To solve this problem, in this study, the researchers have developed a technology that enables nanopillars (diameter φ500 nm) to pass through in only a particular direction, and improve the separation resolution at faster separation speeds.
