Analysis of 3D nanoclaws formation conditions. a–c Three models of bacterial capture at high flow velocity depending on the E of the NWs. a The bacteria loaded on bending surface of soft NWs (E < 1 GPa) will fall off readily. b Adsorbed bacteria can dynamically desorb from stiff NWs (E > 2 GPa) surface as the shear force of the blood stream. c 3D nanoclaws generated by bendable moderate NWs (1 GPa < E < 2 GPa) prevent the immobilized bacteria from washing away at high flow velocity. d The flow field around a single NW, wherein the arrow indicates the flow direction and the contour lines represent fluid flow velocity of different levels. e The magnified region of flow distribution illustrates that the von Mises stresses concentrate at the bottom of a single NW. The deformation of a NW (E = 0.06 GPa) is 1.65 μm at 10 cm s−1 velocity. f Comparison of the deformation of single-crystalline and polycrystalline NWs under different flow velocities
