The faster the separation speed, the better the separation resolution ―Nanotechnology makes it possible

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.
This study was published in Nano Letters on April 16, 2015.
