Culture vessel with rough, water-repellent surfaces for observation
The granted patent US12071604B2 introduces a specialized culture vessel designed for holding biological samples alongside a culture solution, facilitating observation under epi-illumination. The vessel features one or more recesses, each characterized by a flat bottom surface and an upward-extending side surface. Notably, the side surface is equipped with a rough texture, defined by an arithmetic mean roughness ranging from 0.18 µm to 5.0 µm. This rough surface is integral to the vessel's functionality, as it enhances the interaction between the biological sample and the culture solution.
Further specifications detail the rough surface's characteristics, including the presence of flaws with widths between 25 µm and 10 µm, and a flaw spacing of 30 µm to 60 µm. The roughness is consistently distributed along the side surface, extending from the upper to the lower ends. The patent also outlines various methods for creating this rough surface, such as sandblasting, grinding, and chemical etching. Additionally, the culture vessel may be configured as a well plate containing multiple recesses, thereby increasing its utility in biological research and experimentation.
