Russian researchers from the Papanin Institute for Biology of Inland Waters of the Russian Academy of Sciences have patented a device that allows clear viewing of aquatic microorganisms, including translucent and transparent species. This was announced by the inventor Mikhail Dudakov.
The development is an improved Bogorov camera, used for analyzing water samples for over a hundred years. The camera consists of a plate with recesses where the water sample is poured. The researcher can accurately track the areas being studied.
Microscopes often distort images because the backlight intersects with the boundary of the water sample and air. To solve this problem, scientists created cameras from plastic with a refractive index close to water. LED matrices are installed in the walls of the device. They are illuminated only when interacting with objects inside the samples. Thanks to this, microorganisms "glow" from the inside. A clear image appears on a dark background.
The new device significantly improves the visualization of aquatic microorganisms, opening new horizons for scientific research.
