Russian researchers from the Papanin Institute for Biology of Inland Waters of the Russian Academy of Sciences have patented a device that allows you to clearly see aquatic microorganisms, including translucent and transparent species. This was announced by inventor Mikhail Dudakov.
The development is an improved Bogorov chamber, which has been used to analyze water samples for over a hundred years. The chamber consists of a plate with recesses into which the water sample is poured. The researcher can accurately track the areas being studied.
Microscopes often distort images due to the fact that the backlight intersects with the border of the water and air sample. 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 against a dark background.
The new device significantly improves the visualization of aquatic microorganisms, opening up new horizons for scientific research.
