Workflow for the nanoparticle interactive physiologically based pharmacokinetic (Nano-iPBPK) model development. a Pharmacokinetic data of gold nanoparticles (AuNPs) in adult female rats were collected. b A mechanistic-based PBPK model was calibrated with experimental datasets. c The model was optimized and parameter uncertainty and variability were characterized within a Bayesian framework via Markov chain Monte Carlo (MCMC) simulations. d A multiple-linear regression-based quantitative structure–activity relation (QSAR) model was developed to determine the relationship between key biodistribution parameters and physicochemical properties of AuNPs. e The multi-variate linear regression-based in silico QSAR model was integrated into the PBPK model, and the final model was subjected to evaluation/validation with independent data. f The final PBPK model was converted to a web-based graphical user interface termed Nano-iPBPK
