Fig. 2From: Liquid Crystalline Nanoparticles as an Ophthalmic Delivery System for Tetrandrine: Development, Characterization, and In Vitro and In Vivo EvaluationCharacteristics of TET-LCNPs. a Particle size distribution. b Zeta potential distribution. The TET-LCNPs were diluted tenfold with water; particle size distribution and zeta potential were determined at 25 °C. All determinations were performed in triplicatesBack to article page
