Abstract

Chiral inorganic nanostructures whose circular dichroism can be modulated by magnetic field represent an exciting new development in nanoscience, physics, and chemistry. In a letter published in <i>Nature Nanotechnology</i>, Zhuang et al. describe a new method for nanoscale engineering of such structures taking advantage of double buffer layers on the lattice-mismatched semiconductor nanorods. This approach enables one incorporate a magnetic Fe<sub>3</sub>O<sub>4</sub> nanostructures and obtain strong chiroptical activity of achiral semiconductor particles under an external magnetic field.
