Bio Nanological Sealants
Bio-nanological sealants are any compound of organic and non-organic materials that serve to form barriers or seals. In general usage, the term 'bio-nanological sealant' usually refers to compounds of a medical nature, also called biofoam, though technically it is a blanket term that can be applied to any compound of this type.
With recent advances in both nano-technology and bio engineering, some fields of study have found that combining these technologies yield better results than either can achieve separately. In some cases, such as with biofoam, the nanobots act as temporary sealants for breaks in the tissue walls of blood vessels, while the biological component consists of a coating of protein receptors which make the bots invisible to white blood cells. These protein receptors also attract red blood cells, and form the latticework needed to repair breaches until the host organism regenerates the cells to repair the defect natively. Other common medical uses for these types of sealants are nano-gauze, and Neoskin, a substance that is sprayed on hands and forms a second skin, protecting the wearer from the effects of touching anesthetic, while also preventing the spread of germs.
Other compounds of this type include industrial materials such as organic mortar, used to seal large structural bulkheads.
