Correction to: Morphological evolution of ZnO nanostructures with hydrothermal oxidation time and their electrochemical glucose sensing properties
In Figure 3 (a) the axis title as well as units are inadvertently mentioned as “Wavenumber (cm−1)”, which should be read as “Wavelength (nm)”. In the same Figure, the peak labels are mistakenly mentioned with uni...
