From: Carbon nanotube–liposome supramolecular nanotrains for intelligent molecular-transport systems

(a) Concept of artificial molecular signalling. Black arrows show the direction of CNT–liposome nanotrain movement. (b) Direct observation of enzymatic reaction triggered by artificial molecular signalling. The white arrow indicates the irradiation position of the laser beam. Magnification: X20. Laser power: 700 mW (69 mW μm−2). Applying voltage=100 V. Scale bars, 200 μm.
