Liquid Crystals Extend Electrophoresis

Employing a liquid crystalline fluid phase opens up electrophoresis to separating symmetrical or uncharged particles
Department: Science & Technology
Keywords: electrophoresis, separations, liquid crystals

Employing a liquid-crystalline fluid phase, researchers at Kent State University’s Liquid Crystal Institute have extended the capability of electrophoresis to include separating symmetrical or uncharged particles (Nature 2010, 467, 947). Electrophoresis is usually performed in an isotropic fluid such as water with direct current, conditions under which separations are typically limited to charged or highly asymmetric species. Oleg D. Lavrentovich, Israel Lazo, and Oleg P. Pishnyak instead used a nematic liquid crystal as . . .
