The development of artificial micromotors is one of the greatest challenges of modern nanotechnology. Even though many kinds of motors have been published in recent times, systematic studies on the influence of components of the fuel solution are widely missing. Therefore, the autonomous movement of Pt-microtubes and Pt-covered silica particles is comparatively observed in the presence and absence of surfactants in the medium. One representative of each of the three main surfactant classes - anionic (sodium dodecyl sulfate, SDS), cationic (benzalkonium chloride, BACl) and non-ionic (Triton X) - has been chosen and studied.
人工微马达的发展是现代纳米技术面临的最大挑战之一。尽管近年来已经发表了多种类型的马达,但关于燃料溶液成分影响的系统研究却普遍缺乏。因此,比较观察了在介质中存在和不存在表面活性剂的情况下铂微管和铂包覆二氧化硅颗粒的自主运动。选择并研究了三种主要表面活性剂类别中的每一种的一个代表——阴离子型(十二烷基硫酸钠,SDS)、阳离子型(苯扎氯铵,BACl)和非离子型(曲拉通X)。
