a 3D molecular packing showing the α-, β- and δ-form of D-Mannitol. C: gray, H: white, O: red and intermolecular hydrogen bonds are depicted by dashed lines. b AFM image and (c) corresponding height profiles of two selected crystals deposited by gas blow coating of 0.0025 M aqueous solution at a pressure of 1 bar, indicated by the blue and red lines in panel b. d The Raman spectrum of an individual nanorod on silicon. The Raman spectrum of the silicon substrate (in black) was also measured for reference and was subtracted from the overall spectrum (in red) for clarity. The Raman spectrum in green shows the typical peaks associated to the β-form of D-mannitol.
