Shear-Targeted Drug Delivery1

Platelet-sized nanoparticle aggregates deliver nanoparticles-complexed with a therapeutic payload.
Nanoparticles are biocompatible, biodegradable polymers in current FDA-approved products.
Nanonitrate (ShearFlow) contains FDA-approved nitroglycerin as its payload.

Specificity

⎖ ShearFlow Nanoparticle only release in areas of high shear stress.</br>
⎖ (i.e. targets collateral vessels >100dyne/cm2).

Localized vasodilation

⎖ Upon release, ShearFlow Nanoparticles bind to vascular endothelium immediately, producing a potent localized vasodilation.

By releasing therapeutic agents precisely at sites of elevated shear stress nanonitrate can minimize systemic side effects & maximizes local efficacy.
