Nanotechnology drug carriers work through various mechanisms to deliver drugs effectively:
Passive targeting: Utilizes the enhanced permeability and retention (EPR) effect, where nanoparticles accumulate in tumor tissues due to leaky vasculature. Active targeting: Involves functionalizing the surface of nanoparticles with ligands that bind to specific receptors on target cells, improving specificity. Controlled release: Nanoparticles can be engineered to release drugs in response to specific stimuli, such as pH, temperature, or enzymes.
