摘要：
The present invention relates to a nanoparticle, a preparation method thereof, a stone removing device and its application. The nanoparticle includes a nanoparticle core made of a magnetic material, and a nanoparticle shell formed by attaching a surface modifier monomer to the nanoparticle core with an initiator and/or a crosslinking agent. The prepared nanoparticle can surround stones in ureter, and then small stone remaining in body can be removed quickly without damage from the body under the action of an externally applied magnetic field, that is, the stone can be drawn and moved without injuring ureteral wall, and meanwhile the nanoparticles are placed conveniently without shift.
