Fig. 4: Nano-calligraphy created with nanowires.
From: Nano calligraphy via optical electro-aligning manipulation
a A single nanowire is trapped by OT in electric field and draws the outlines of the letters “B”, “I” and “T”. Scale bar: 5 µm. b A single nanowire draws the outline of a Loong. Scale bar: 5 µm. c Three nanowires are captured by three optical traps and draw the outline of the school emblem in parallel. Scale bar: 5 µm. More details in Fig. S7 and Movies S3-5
