Researchers from the Skolkovo Institute of Science and Technology, together with their colleagues, have discovered an optical effect in diatom algae that could form the basis of new technologies in solar energy, photonics, and biosensing. This was reported by the press service of
Skoltech, a partner of TV BRICS.

The patterns on the shells of single-celled algae of the Coscinodiscus oculus-iridis species turned out to be not only beautiful but also functional. Scientists found that thanks to these structures, the algae are able to use the so-called Talbot effect – a diffraction phenomenon in which light is focused inside the shell. It is assumed that this helps to capture sunlight more efficiently for photosynthesis.

“They may do this due to the optimal arrangement of chloroplasts that absorb light,” noted the first author of the study, Associate Professor at the Skoltech Centre for Engineering Physics, Sergey Dyakov.

The unique properties of algae are inspiring researchers to develop new technological solutions – from photosensitive coatings and sensors to components of solar panels and artificial photosynthesis systems capable of converting sunlight into fuel.
