How is Surface Modification Applied in Biomedical Nanotechnology?
In biomedical nanotechnology, surface modification plays a crucial role in the development of nanocarriers for drug delivery. Modifying the surface of nanocarriers ensures: 1. Targeted Delivery: By attaching targeting ligands, nanocarriers can specifically bind to diseased cells, increasing the efficacy of the treatment. 2. Stealth Properties: Surface modification with polyethylene glycol (PEG) can provide a ‘stealth’ effect, prolonging the circulation time of nanocarriers in the bloodstream. 3. Controlled Release: Functionalizing the surface with stimuli-responsive materials allows for controlled drug release in response to specific environmental triggers.
