From: Characterization of physicochemical properties of ivy nanoparticles for cosmetic application
The influence of pH on ivy nanoparticles. a Size distributions of ivy nanoparticles dispersed in buffers with different pH values: (a) pH 4.0, (b) pH 5.0 (c) pH 6.0, (d) pH 7.4, (e) pH 8.0, (f) pH 9.0, (e) pH 10.0, b Mean sizes of ivy nanoparticles dispersed in buffers with 7 different pH values, and c UV extinction spectra of ivy nanoparticles dispersed in buffers with 7 different pH values. The panels are the amplification of the corresponding areas of the UV extinction spectra.
