Briefings

Scientists at IOCB Prague demonstrated that light can suppress random molecular motion by up to five orders of magnitude, slowing relative rotation within a molecule. This breakthrough enables the creation of more complex molecular machines by stabilizing internal molecular structures. The study, published in October 2026, uses specific wavelengths of light to achieve this effect without external mechanical forces.

Key points

• Light-induced suppression of random molecular rotation by up to five orders of magnitude (100,000x reduction in relative motion).
• Achieved by scientists at IOCB Prague using controlled light wavelengths to stabilize internal molecular components.

Context

Molecular motion is fundamental to biological and chemical processes, but thermal energy typically causes constant internal rotation. This research provides a method to halt that motion, which is crucial for engineering stable molecular machines.

Limitations

Evidence is limited to a single study from October 2026. The specific light wavelengths and exact molecular structures stabilized remain undefined. No long-term durability or scalability data is provided.
