How are Nanoparticles Functionalized for Targeting?
Functionalization involves attaching targeting ligands to the surface of nanoparticles. This can be done through: 1. Covalent Bonding: Strong and stable but may require complex chemistry. 2. Non-Covalent Bonding: Easier to achieve but less stable. 3. Bioconjugation: Uses biological molecules to achieve functionalization.
