Figure 6From: Characterization of physicochemical properties of ivy nanoparticles for cosmetic applicationUV irradiation influence on ivy nanoparticles. a Schema of UV irradiation test. Irradiation time was controlled by removing coverslips at scheduled time (0 hour, 8 hours and 11hours), and b UV spectra of ivy nanoparticles after treatment with different UV irradiation time. The BSA with the same concentration was treated based on the same procedure as the control.Back to article page
