👉 Microrhopias are small, closely related particles that can be found in various environments. These particles have a diameter of less than 10 nanometers (nm), which is comparable to the size of a grain of sand or a bacterium. They are often found in the microenvironment around living organisms and play important roles in their growth, metabolism, and survival. Microrhopias can be classified into two main categories: intracellular microrhopias and extracellular microrhopias
