Light can now be used to achieve ever better control of microparticles and nanoparticles. Researchers at the Max Planck Institute for the Science of Light in Erlangen are now able to use a laser to cause tiny particles to rotate around an axis perpendicular to the light beam – a particle thus rotates like the wheel of a bicycle in its direction of motion. The researchers achieved this by creating a photonic wheel: light with purely transverse angular momentum. This state of light was previously unknown. Physicists assumed that all light had propeller-shaped, longitudinal angular momentum. The new way of controlling light waves makes optical tweezers, which can be used to grip and manoeuvre cells and other micro-objects and nano-objects, more versatile.
