a Diagram of the enzyme-assisted glucose-powered nanofishes manufactured in the microchannel. b Dynamic design, 3d EBL printed, and the directional actuation of the nanofishes. Scale bars in (b), fluorescence microscope photographs (right 2 images), 10 μm. c Near-infrared (NIR) light-activated, temperature, and pH-triggered dissolution of the ambient sensing nanofishes for the controllable payload release and device lifetime. Scale bar in (c), NIR microscope photographs (first row), 20 μm; fluorescence microscope photographs, 20 μm (second row), and 5 μm (third row), respectively.
