(a–c) and (d–f) Optical and Stereo microscope images of PDMS spindle knot on fiber surface with different size spindle-knots respectively (a–c scale bar: 60 μm, d-f scale bar: 200 μm). (Spindle knots with maximum volume: VB, spindle knots with middle volume: VM, spindle knots with minimum volume: VS).
