Nanodisks are tiny, disk-shaped structures typically made of lipids or other materials, measuring just a few nanometers in diameter. They are often used in scientific research and biotechnology due to their unique properties, such as their ability to encapsulate drugs or deliver genetic material into cells. Their small size allows them to interact with biological systems at the molecular level. These structures can also serve as models for studying membrane proteins and cellular processes. Researchers utilize nanodisks to better understand the behavior of cell membranes and to develop new therapies for diseases. Their versatility makes them valuable tools in the fields of nanotechnology and pharmaceuticals.
