What Are the Different Types of Nanoparticles Used?
Various nanoparticles are used in medical imaging, each with distinct advantages:
Quantum Dots: These semiconductor nanoparticles exhibit unique optical properties and can be used for high-resolution imaging. Gold Nanoparticles: Known for their biocompatibility and strong scattering properties, they are used in optical imaging techniques. Superparamagnetic Iron Oxide Nanoparticles (SPIONs): These are widely used in MRI to enhance contrast. Silica Nanoparticles: These are used in both optical and ultrasound imaging due to their stability and functionalizability.
