How Are Nanoparticles Used in Imaging Blood Vessels?
Nanoparticles can be functionalized with specific ligands or antibodies that bind to markers on blood vessels or diseased tissue. Once injected into the bloodstream, these nanoparticles accumulate in the targeted area, enhancing the contrast and allowing for detailed imaging. Techniques like Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and Positron Emission Tomography (PET) can then provide high-resolution images.
