Fig. 3From: Verification of nanoparticle formation, skin permeation, and apoptosis using nobiletin as a methoxyflavonoid derivativeChanges in particle size and zeta potential of nanoparticles of Sol/ASC-DP/NOB = 8/1/1 nanoparticles after the storage at 25 °C day 1 to day 7 in distilled water (DW), 5% glucose solution, and saline. Each point represents the mean ± S.D. a Day 1: saline, b day 7: saline, c day 1: 5% glucose, d day 7: 5% glucose, e day 1: DW, and f day 7: DWBack to article page
