National University of Singapore (NUS) scientists used biological components to encode and store images on live cells.

Said NUS' Poh Chueh Loo, "Using optogenetics—a technique that controls the activity of cells with light akin to the shutter mechanism of a camera—we managed to capture 'images' by imprinting light signals onto the DNA 'film'."

The researchers marked the images for identification using barcoding methods similar to photo labeling.

They utilized machine learning algorithms to structure, sort, and reassemble the images in a manner resembling digital cameras' data capture, storage, and retrieval processes.

The system is easily reproducible and scalable compared with previous DNA data storage techniques.
