荷兰乌德勒支大学和菲利浦研究所的化学家发展了用电场调节通过液体的光流技术。其基础是“纳米棒”光吸收现象 (金属颗粒直径 12～ 2 2 nm,长 4 0～ 730 nm) ,该技术允许科学家用电场改变棒的取向来选择通过液体的光量。三十年代以来就有利用纳米棒光吸收性质的专利申请 ,但由 Chemists at Utrecht University and the Philips Institute in the Netherlands have developed optical flow technology that uses electric fields to regulate liquid flow. The basis of this is the “nanorods” absorption of light (metal particles 12 to 22 nm in diameter and 40 to 730 nm in length) that allow scientists to select the amount of light passing through a liquid using an electric field that changes the orientation of the rod. Since the thirties there have been patent applications that make use of the light absorption properties of nanorods, but from
