Magnetic DNA Origami Nanorotors
Advanced Materials, EarlyView.Magnetic actuation is a powerful and broadly applicable actuation mechanism due to its programmability and compatibility with biological entities. Here we demonstrate magnetic DNA origami nanorotors (MADONAs) by assembling magnetic nanocubes on DNA origami.

Advanced Materials, EarlyView.Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams
Advanced Optical Materials, EarlyView.Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

A Lorentz force MEMS magnetometer
2016 IEEE SENSORS, 2016 This paper presents a Lorentz force magnetometer with a MEMS resonator structure as a sensor. Magnetometer composed of a resonator and a grill structure. The grill structure reduces the heat generation due to the current required to generate the Lorentz force.
