2.5.2. Polydispersity Index (PDI) and Droplet Size (PS)

The PDI and droplet size were determined using a Nano-ZS Malvern Zetasizer (Malvern Instruments, Worchester, UK) using the dynamic light scattering (DLS) mode. The sample was prepared by dispersing 500-µL aliquots of the saturated nanoemulsion in 50 mL HPLC grade water and placed into a 12.5 <sup>×</sup> 12.5 <sup>×</sup> 45 mm BRAND® disposable cuvette (BRAND GmbH <sup>+</sup> CO KG, Wertheim, Germany).
