Nano probe by the signal components and affinity components, the former refers to molecular imaging contrast agent such as nanoparticles or markers, the latter assignment, or antibody specificity molecular body, make it combined with imaging target specificity, using high precision imaging technology for molecular information, nanoprober combined treatment can also realize the integration of targeted therapy.
Materials that can be used to construct nanoprobes are as follows:

● Magnetic nanoparticles as magnetic resonance contrast agent

● Semiconductor quantum dots as optical contrast agents

● Gold nanoparticles as CT contrast agent/Raman probe/photoacoustic probe

● Microbubbles as ultrasound contrast agent, etc.
