How Do Nanomaterials Accumulate in Biological Systems?
In biological systems, nanomaterials can accumulate through ingestion, inhalation, or skin contact. Once inside the body, they may interact with cells and tissues in various ways. Some nanomaterials can cross biological barriers, such as the blood-brain barrier, leading to accumulation in specific organs. Factors influencing this process include the size, shape, surface charge, and coating of the nanomaterials. The body's ability to clear these materials also plays a critical role in determining their accumulation.
