Researchers introduce spin orbit torque (SOT) devices to experimentally realize in-memory analogue mathematical operations such as summation, subtraction and four-quadrant multiplication, to implement general-purpose applications such as image or signal processing for edge computing. In addition to nonvolatility and scalability, the CMOS-compatible SOT technique further possesses low energy consumption, high speed and endurance. Therefore, SOT devices offer an avenue for dense in-memory analogue computing paradigms.

One convenient way to manipulate nanoscale objects with remote controllability is actuation and propulsion by light, which is largely based on optical and photothermal-induced forces. Unfortunately, the output of optical and photothermal-induced forces is small and speed is slow. This changes with a novel and intriguing nanoactuation system: plasmonic nanodynamite. This system can be optically triggered to eject gold nanobullets with an initial speed of up to 300 m/s.

The controlled rotation of micro- and nanoscale objects plays a crucial role in sensing, imaging, biomedicine, and manufacturing. What makes light-driven micro- and nanorotors so promising for many applications is their non-contact, fuel-free operation. It has remained challenging for simple and low-power optics to achieve light-driven rotation of a wide range of objects, including optically symmetric synthetic particles and biological cells. A novel platform elegantly addresses this issue by achieving the rotation of various particles and live cells using an arbitrary low-power laser beam.

Magnetic manipulation of nano- and microscale objects is a remote and non-invasive technology with potentially numerous applications in material sciences and life sciences, such as for instance drug delivery. However, a limitation of this technology is that it can only be applied to certain materials with magnetic response, i.e., ferromagnetic or superparamagnetic materials. A new technique allows to incorporate magnetic nanoparticles onto the nonmagnetic skeleton.
