Owing to the high-dimensional parameter space involved, targeted nanoparticle design and medical use are amenable to multiscale computational modeling to provide predictive values of appropriate characteristics for manufacture and clinical application while reducing the time, expense, and other resources necessary for otherwise large scale experimentation. In the past 3 years, Web of Science keyword “functionalized nanoparticle” search return 2481 publications. However, the published literature for associated theoretical/computational aspects of nanoparticle-based targeted drug delivery remains limited. This suggests that a physiologically sound, theoretically robust, and computationally tractable model is critical for rational design of nanoparticles for drug delivery. In this project, we propose combining fundamental principles of statistical mechanics and colloidal hydrodynamics to tackle the design of surface-functionalized nanoparticles that can self-assemble and bind to the target cells. In Year 3, we will develop a unified theoretical and computational framework that simultaneously bridges the dynamical relaxations of nanoparticles, functionalizing ligands, cell receptors, and the cell membrane. This consistent consideration of hydrodynamic effects makes the proposed project unique and the predictions truly physiologically relevant.統計力學流體力學多尺度模擬標靶藥物傳遞功能性奈米粒子statistical mechanicshydrodynamicsmultiscale modelingtargeted drug deliveryfunctionalized nanoparticles
