  • Microbubble-extracellular vesicle complexes
    Publication number: 20230136448
    Abstract: Disclosed herein are a microbubble-extracellular vesicle complex, a production method therefor, and a system for driving the same. In one aspect, preferred microbubble-extracellular vesicle complexes may comprise an ultrasound contrast agent-based microbubble, an extracellular cell derived from a natural killer cell (NK cell), a human glial cell, or a human mesenchymal stem cell, and a coupling medium and can be derive in a 3D mode using ultrasonic waves and deliver a drug loaded in the extracellular vesicle to a target site.
