Abstract
- Gold nanoshells currently attract increasing researchinterestsdue to the important role in many subjects. For practical applications,random arrangement of the nanoparticles is often unfavored so thatthe assembly of gold nanoshells is becoming a central issue. We hereproposed to utilize time-variant magnetic field to direct the assemblyof gold nanoshells. It was discovered that the alternating magneticfield can mediate the vortex-like assembly of gold nanoshells. Themechanism was explored and thought to be relative with the electricfield of induction which caused the thermal gradient on the substrateand the electric force. The vortexlike structure as well as the assemblymechanism will play an important role in research and applicationof gold nanomaterials. [ABSTRACT FROM AUTHOR]
