摘要：
Core-shell nanoparticles containing both iron oxide and gold are proposed as a new tool for in vitro biosensing applications. The surface plasmon resonance of gold was used to track the positions of individual particles smaller than the optical diffraction limit. With a large magnetic field gradient from a tip made of a soft magnetic material, particles can be collected and later released.
