What Are Common Types of Nanoparticles Used in Bioimaging?
Several types of nanoparticles are commonly used in bioimaging, including:
Quantum Dots: These are semiconductor nanoparticles that exhibit unique optical properties, such as size-tunable fluorescence, making them ideal for imaging applications. Gold Nanoparticles: Known for their excellent biocompatibility and strong optical absorption, gold nanoparticles are widely used in imaging and diagnostic applications. Magnetic Nanoparticles: These particles, often made of iron oxide, are used in magnetic resonance imaging (MRI) to enhance contrast and provide detailed images of tissues. Silica Nanoparticles: These nanoparticles can be functionalized with various biomolecules, making them versatile tools for targeted imaging and drug delivery.
