Friction and adhesion between two β-cyclodextrin functionalized surfaces can be switched reversibly by external light stimuli. The interaction between the cyclodextrin molecules attached to the tip of an atomic force microscope and a silicon wafer surface is mediated by complexation of ditopic azobenzene guest molecules. At the single molecule level, the rupture force of an individual complex is 61 ± 10 pN.
两个β-环糊精功能化表面之间的摩擦力和粘附力可通过外部光刺激进行可逆切换。附着在原子力显微镜尖端的环糊精分子与硅片表面之间的相互作用是由双位偶氮苯客体分子的络合介导的。在单分子水平上，单个络合物的断裂力为61±10皮牛。
