Original article: The Journal of Chemical Physics 145 (7), 074117 (2016) In the abstract and on page 2, right column, first paragraph, of Ref. 1, the value m=±1/(270 nm) of the spontaneous curvature m was erroneously assigned to spherical hard-core particles with a diameter of 1 nm but applies instead to such particles with a radius of 1 nm. Furthermore, in Table I of Ref. 1, the numerical values of the spontaneous curvature m for the hard-core system are obtained from Eq. (19) for variable particle radius Rhc as well as for constant bending rigidity κ=20kBT (instead of κ=10−19 J) and constant membrane thickness ℓhw=4 nm. Glucose molecules have a hydrodynamic radius of 0.36 nm at room temperature.2 Using the particle radius Rhc=0.36 nm and the previously mentioned membrane parameters, Eq. (19) predicts the spontaneous curvatures m=±1/(846 nm) and m=±1/(423 nm) when the two sides of the membrane are exposed to aqueous glucose solutions with a concentration difference of 100 mM and 200 mM, respectively
