Abstract: A method for labeling exosomes with a radioactive substance using an amine group on surfaces of the exosomes includes providing a cell-derived exosome, treating a surface of the exosome with N-hydroxysuccinimide-azadibenzocyclooctyne (NHS-ADIBO), and mixing the treated exosome with N3-introduced chelator-radioactive substance to conduct a reaction between the chelator and an amine group present on the surface of the exosome, wherein the radioactive substance is introduced inside the exosome by the above reaction. The exosomes can be stably labeled at high labeling efficiency, and the exosomes can be favorably used as an agent for nuclear medicine imaging and therapeutic imaging for confirming the biological distribution of exosomes and whether the exosomes move to target organs and target diseases in animals including a human being.

Abstract: Provided are a method for simultaneously detecting fluorescence and Raman signals for multiple fluorescence and Raman signal targets, and a medical imaging device for simultaneously detecting multiple targets using the method. The method includes: injecting at least one marker particle comprising Raman markers and receptors into the body of an animal, which can be a human; irradiating a laser beam onto the body of the animal; and detecting the optical signals emitted by the marker particle after the irradiation of the laser beam separately as fluorescence signals and Raman signals. The simultaneous detection of multiple targets may be performed even without scanning optical signals emitted by the marker particle individually with different optical fibers. As an examination may be performed by injecting surface-enhanced Raman marker particles, weak Raman signals may be augmented so as to obtain a more accurate diagnosis result in real time.
