A remarkable new method of distinguishing chiral (mirror-image) molecules could eventually detect distortions inside quantum and soft materials, find abnormal protein aggregates linked to disease, and more.

Researchers at Osaka Metropolitan University have succeeded in printing uniformly sized droplets with a diameter of approximately 100 µm using a liquid film of fluorescent ink. This ink, with a viscosity roughly 100 times that of water, was irradiated with an optical vortex, resulting in prints of exceptional positional accuracy at the micrometer scale.
