Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conventional methods—plastic particles with a diameter of less than one micrometer commonly referred to as “nanoplastics.” Such tiny particles can even be absorbed into living cells.
