Fluorimetry analysis of the retention of encapsulated 5-(and-6)-carboxyfluorescein (CF) by non-lyophilized (NL; part of the solution that was stored at 4 °C for 19 hours, while the lyophilized part was drying) and lyophilized (L; rehydrated right after lyophilization) lipid nanocapsules. Retention of CF was calculated as % Retention = [(Fa’ – Fb’)/Fa’]/[(Fa – Fb)/Fa]x100%, where Fb and Fa is the fluorescence intensity before and after the addition of detergent into a nanocapsule solution right after nanocapsules were made; and Fb’ and Fa’ is the fluorescence intensity before and after the addition of detergent to a lyophilized (L) or a non-lyophilized (NL) sample.
