What Are the Types of Nanoparticles Used in Imaging?
Several types of nanoparticles are commonly used in imaging, each with its unique advantages:
Quantum dots: These are semiconductor nanoparticles that exhibit bright and stable fluorescence, making them ideal for optical imaging. Gold nanoparticles: Known for their excellent biocompatibility and strong scattering properties, they are used in optical and electronic imaging techniques. Iron oxide nanoparticles: These are commonly used in MRI due to their superparamagnetic properties, which significantly enhance image contrast. Silica nanoparticles: Often used as carriers for fluorescent dyes, they provide stable and bright signals for imaging applications.
