(a,b,e) Design drawings of the microdevices based on bifurcated, simple-maze and complicated-maze microchannels, respectively. Red arrows show the direction of CNT–liposome nanotrain movement. Green and pink lines indicate the shortest and the longest paths, respectively. S, start; G, goal; G1, goal 1; G2, goal 2; G3, goal 3. (c) A direct observation of the nanotrain’s behaviour in the bifurcated microchannel after applying a voltage (300 V). Image of the nanotrain movement showing the shortest path between S and G. Scale bar, 100 μm. (d) A direct observation of the nanotrain behaviour in the simple-maze microchannel after applying a voltage (300 V). Image of the nanotrain movement showing the route for the shortest path in the maze. Scale bar, 100 μm. (f) A direct observation of the nanotrain behaviour in the complicated-maze microchannel after applying voltage (300 V). Image of the nanotrain movement showing the quickest route from S to G for a more complex maze. Scale bar, 500 μm.
