Figure 4

(a) UV absorption spectra of increasing amount of PLA/5-LG NCs solution (5, 10, 20, 30, 40 and 50 μL): the peak at 275 nm corresponds to PLA while the shoulder at 240 nm corresponds to LG absorption; (b) intensities of the peak at 240 nm for increasing amounts of PLA/5-LG NCs; (c) calibration curve of LG essential oil; and (d) calculation of LG oil content in 5 μL of PLA/5-LG NCs.
