A Cryo-Electron Microscopy (CryoEM) image of lipid-coated Zinc Oxide Nanocrystals (L-ZnO), depicting the ZnO nanocrystals surrounded by a visible lipid bilayer, evidenced by the black arrows. Scale bar is 50 nm. B Dynamic Light Scattering (DLS) of uncoated (ZnO) and lipid-coated (L-ZnO, YSA-L-ZnO) in water and C in cell culture media; D Z-Potential of uncoated (ZnO) and coated (L-ZnO, YSA-L-ZnO) in water; E Spinning disk confocal fluorescence microscopy image of YSA-L-ZnO, where ZnO and YSA peptide were fluorescently labelled with Atto550 and FITC dyes, respectively, thus visible as red and green signals; F Hemocompatibility studies comparing the clotting time of human plasma after calcium chloride addition in absence and in presence of ZnO, L-ZnO or YSA-L-ZnO
