The Dimova group at the Max Planck Institute has discovered a method to control cellular interactions using light of different colors.

This technique enables the targeted delivery of drugs directly into cells by manipulating biomolecular condensates.

They have created lab-made giant vesicles to mimic cellular processes, observing changes in membrane behavior when exposed to light.

Ultraviolet light causes the membrane to grow and encapsulate condensates; blue light reverses this, releasing the condensates.

The discovery has significant therapeutic implications, potentially offering a non-invasive way to manage cellular dynamics.

The method is sustainable, avoids using living organisms, and could transform treatments for cellular disorders.
