Summary
This study predicts nanoparticle deposition in patient-specific arteries, finding that vascular architecture and nanoparticle size significantly impact where particles adhere. This allows for personalized nanoparticle selection for optimized therapeutic delivery.
Area of Science:
- Biomedical Engineering
- Computational Fluid Dynamics
- Nanomedicine
Background:
- Nanoparticle delivery is crucial for targeted therapies.
- Predicting nanoparticle deposition in complex vasculature remains challenging.
Purpose of the Study:
- To develop a computational framework for predicting nanoparticle deposition in patient-specific arterial trees.
- To investigate the influence of vascular architecture, flow, receptor density, and nanoparticle properties on deposition.
Main Methods:
- Patient-specific vascular geometry reconstructed from CT angiography.
- Isogeometric analysis framework with specialized boundary conditions for nanoparticle adhesion.
- In vitro validation using a parallel plate flow chamber.
Main Results:
- Particle adhesion is highly sensitive to patient-specific factors like branching angles and receptor density.
- Adhesion patterns correlate with wall shear rates.
- Larger particles (2.0 µm) deposit more in lower arterial branches, while smaller particles (0.5 µm) deposit more in upper branches.
Conclusions:
- The computational framework enables prediction of nanoparticle deposition.
- Patient-specific attributes can be leveraged to optimize nanoparticle properties for personalized therapeutic interventions.
