LCNPs had an average hydrodynamic diameter of 179 ± 19 nm and a polydispersity index (PDI) of 0.172 ± 0.005, determined by dynamic light scattering (DLS) (Fig. ). Cryogenic Transmission Electron Microscopy (cryo-TEM) revealed the structure of the dispersed LCNPs, with a fast Fourier transform (FFT) image analysis, confirming the internal Im3m crystal structure (Fig. ).
