Nanomedicine
The medical application of nanotechnology utilizing engineered nanoparticles for disease diagnosis, targeted drug delivery, and therapy.
Governing formula
EPR Effect: Enhanced Permeability and Retention in Tumors
SI unit
nm (Nanoparticle Diameter ~10–100 nm)
In depth
Engineered nanoparticles (10–100 nm) exploit leaky tumor vasculature (EPR effect) to passively accumulate in cancerous tissue, delivering localized chemotherapy doses while minimizing systemic toxicity.
Examples in the real world
Gold nanoparticles absorbing near-infrared laser light for localized photothermal tumor ablation.
