Correction: A non-sacrificial method for the quantification of poly(ethylene glycol) grafting density on gold nanoparticles for applications in nanomedicine

Abstract

Correction for ‘A non-sacrificial method for the quantification of poly(ethylene glycol) grafting density on gold nanoparticles for applications in nanomedicine’ by Jun Lu et al., Chem. Sci., 2019, 10, 2067–2074, https://doi.org/10.1039/C8SC02847H.

The authors regret that on page 9 of the ESI, the Stokes–Einstein equation and calculated diffusion coefficient (D) were incorrect. The corrected equation and calculated diffusion coefficient are shown here:

The value for the diffusion coefficient of pure gold nanoparticles (GNPs) on page 2068 of the main article should therefore be 3.81 × 10⁻¹¹ m² s⁻¹.

The ESI available online has now been updated to reflect these changes.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
