磁场可用于控制水滴在非图案化硅纳米线超疏水表面上的移动。通过将可磁化羰基铁微粒引入液体中来控制水性和生物流体的液滴。操作的关键要素，如运动，聚结，水和生物液滴的分裂，以及分析物的电化学测量演示。超疏水表面的制备使用气-液-固（VLS）生长系统，然后用全氟化烃分子涂层。液滴由具有范围从0.1至10重量%的可磁化微粒浓度的水性和生物流体悬浮液制成。(C)2006 Elsevier B. V.保留所有权利。
Magnetic fields can be used to control the movement of aqueous drops on non-patterned, silicon nanowire superhydrophobic surfaces. Drops of aqueous and biological fluids are controlled by introducing magnetizable carbonyl iron microparticles into the liquid. Key elements of operations such as movement, coalescence, and splitting of water and biological fluid drops, as well as electrochemical measurement of an analyte are demonstrated. Superhydrophobic surfaces were prepared using vapor-liquid-solid (VLS) growth systems followed by coating with a perfluorinated hydrocarbon molecule. Drops were made from aqueous and biological fluid suspensions with magnetizable microparticle concentrations ranging from 0.1 to 10 wt%. (C) 2006 Elsevier B.V. All rights reserved.
