Abstract
Correction for ‘Shape-controlled anisotropy of superparamagnetic micro-/nanohelices’ by Alexander M. Leshansky et al., Nanoscale, 2016, 8, 14127–14138, https://doi.org/10.1039/C6NR01803C.
The authors regret that in Fig. 3 of the original manuscript, images B and C were interchanged without a corresponding update to the caption. Fig. 3B shows the normal helix, while Fig. 3C depicts the binormal helix. The figure and the updated caption are therefore as displayed herein.

| Fig. 3 Illustration of the regular (A), normal (B) binormal (C) and MPC (D) helical micropropellers with two full turns, R/r = 1.25, Θ = 60° and N = 500 magnetic inclusions. In B, C and D, the filament cross-section (red dashed lines) aspect ratio is set to 3; the right panel in D shows the horizontal projection/top view of the MPC helix, dashed lines show the elliptical filament cross section at different locations. | ||
Two sentences on page 14132 which reference Fig. 3 are also updated accordingly as below:
“This non-local intrafilament interaction is most pronounced for binormal helices (see Fig. 3C), where elongation of the filament cross-section contributes to preservation of the longitudinal orientation of the easy axis, so that Φ ≲ 20° for all values of Θ”.
“For normal helices the situation is the opposite – elongation of the filament cross-section along the normal vector (see Fig. 3B) contributes to transverse orientation of the easy axis and, therefore, the transition shifts to lower Θ* when compared to the regular helix”.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
