Creation and screening of atovaquone nanoformulations. a Hydrophobic hydroxynaphthoquinone atovaquone was formulated to generate candidate ATQSDN nanoparticles. b ATQSDN library was screened for Z-average nanoparticle diameter after dispersion into water (0.5 mg mL−1, 25 °C); 'hits' (solid bars) were selected for further evaluation. c Eleven ATQSDN 'hits' were evaluated using an in vitro rapid equilibrium dialysis intramuscular depot model assay (SIF) using ATQSDN formulation prepared with 3H-labelled atovaquone
