Nanoparticles can be engineered to have unique properties such as superparamagnetism, fluorescence, or the ability to emit signals under certain conditions. These properties make them ideal for use in various imaging modalities like Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and Positron Emission Tomography (PET). For example, superparamagnetic nanoparticles can enhance the contrast in MRI, while fluorescent nanoparticles can be used for optical imaging.
