The gastrointestinal tract is a complex barrier/exchange system, and is the most important route by which macromolecules can enter the body. The main absorption takes place through villi and microvilli of the epithelium of the small and large intestines, which have an overall surface of about 200 m2. Already in 1922, it was recognized by Kumagai, that particles can translocate from the lumen of the intestinal tract via aggregation of intestinal lymphatic tissue (Peyer’s patch, containing M-cells (phagocytic enterocytes)). Uptake can also occur via the normal intestinal enterocytes. Solid particles, once in the sub-mucosal tissue, are able to enter both the lymphatic and blood circulation.

One of the most significant impacts of TIO2 in factories is its role in photocatalysis. This process involves the acceleration of photoreaction in the presence of light and a catalyst—in this case, TIO2. By harnessing the power of sunlight or artificial UV light, TIO2 can break down organic pollutants into substances, playing a crucial role in environmental remediation efforts within industrial settings. This not only helps factories minimize their environmental footprint but also reduces the costs associated with waste treatment and disposal.
