AI Insight
Researchers from Skoltech and Russian Academy of Sciences institutions recreated the shell structure of a single-celled diatom alga at 2,000 times its natural size to experimentally verify a previously predicted optical effect using terahertz waves. The team successfully demonstrated that the unique patterned structure of the diatom shell can manipulate terahertz radiation in predictable ways. This biomimetic approach provides experimental confirmation of theoretical models for how these microscopic biological structures interact with electromagnetic waves.
Why it matters
The findings could advance medical and biological imaging systems that use terahertz radiation, as well as enable better nondestructive testing methods for industrial quality control. The diatom shell's structure also offers a blueprint for designing compact components that focus and shape wavefronts in terahertz devices, potentially leading to more efficient optical components.
Understand the Science
Researchers from Skoltech—a VEB.RF group institution—and their colleagues at the Kurchatov Institute, the Prokhorov General Physics Institute and the Institute of Solid State Physics of the Russian Academy of Sciences have recreated the patterned shell of a single-celled diatom alga, scaled it up by a factor of 2,000 and used it to confirm a previously predicted optical effect in an experiment with terahertz waves. The findings hold promise for imaging systems in biology and medicine and for nondestructive material quality testing in industry. The supersized shell’s structure suggests new approaches for building compact components that focus and shape wavefronts in terahertz devices. The study was published in Light: Advanced Manufacturing.
