Liquid Crystal Polymers as Intrinsically Magnetic and Programmable Soft Materials for Microrobotics

Small, EarlyView.
Liquid crystal polymers (LCPs) are proposed as intrinsically magnetic, programmable, soft materials for microrobotics. Magnetic torque‐driven manipulation of LCP microobjects is achieved and characterized in terms of the step‐out frequency, reaching ∼0.6 Hz in a ∼250 mT magnetic field. The orientation of LCP microobjects in the magnetic field and their

The rotational propulsion characteristics of scaled-up helical microswimmers with different heads and magnetic positioning [PDF]

2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013
Micro and nanorobots capable of controlled propulsion at low Reynolds number are foreseen to change many aspects of medicine by enabling targeted diagnosis and therapy, and minimally invasive surgery. Several kinds of helical swimmers with different heads actuated by a rotating magnetic field have been proposed in prior works.

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

Advanced Materials, Volume 38, Issue 30, 27 May 2026.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...

Active Particles in Tunable Compressible Environments

Small Science, Volume 6, Issue 5, May 2026.
Gold‐capped active microparticles powered by electric fields plough their way through a matrix of repulsive spheres, shoveling them aside. At high densities and field strengths, an initial strong direction fluctuation may compress the matrix asymmetrically and lead to an asymmetric reaction favoring sustained turns to the same side (spontaneous ...
