Various strategies are employed to achieve target specificity in nanotechnology:
Surface Modification: Functionalizing the surface of nanoparticles with specific ligands, antibodies, or peptides that can bind to target receptors on cells. pH-Sensitive Systems: Designing nanoparticles that release their payload in response to the acidic environment of tumor tissues or intracellular compartments. Magnetic Targeting: Using magnetic fields to direct magnetically responsive nanoparticles to specific locations. Enzyme-Responsive Systems: Creating nanoparticles that are activated by enzymes overexpressed in certain diseases.
