Adv. Funct. Mater. 2017, 27, 1702689 The unit in the y-axis of Figure 5 (c) should be nm/s instead of μm/s. In consequence, the corrected Figure 5 (c) should appear as follows: Figure 5. C) Dependence of the average .lopodial extension velocity on the adhesion strength γ and surface roughness. α here represents the shrinking factor with α = 1 corresponding to the initial MCD topography. Error bar here indicates the standard deviation of simulation results from eight different MCD topographies. For comparison, the measured speeds of growing filopodia on MCD and NCD substrates are also given by the purple and blue cross markers (assuming γ = 9 × 10−5 J m−2), respectively. The above error does not affect the scientific conclusions drawn from the work. The authors apologize for any inconvenience or misunderstanding that this error may have caused.
