Abstract
The present invention relates to nanoparticles, a preparation method thereof, a stone removal device, a magnetic target separation instrument and its application. The nanoparticles include a nanoparticle core made of magnetic materials, and a nanoparticle shell formed by attaching surface modifier monomers to the nanoparticle core with an initiator and/or a crosslinking agent. The prepared nanoparticles can wrap stones in ureter, and then small stones remaining in body can be removed quickly without damage from the body under the action of the magnetic target separation instrument. The stones can be drawn and moved without injuring ureteral wall, and meanwhile be disposed conveniently without easy shift.
