Enzyme-based nanocomplexes and their construction for detoxification of organophosphorus compounds

Abstract

Organophosphorus compounds (OPC) pose a serious threat, as they can have a neurotoxic effect on the human body, even death. In this regard, the main challenge of our times is the search for effective ways of degradation of OPC. In this case, preference is given to biological methods of OPC detoxification, which do not require the use of harsh chemical methods of degradation and are suitable for in vivo use. One of such methods is the use of biocatalysts — enzymes capable of hydrolyzing OPC. To stabilize the activity of enzymes, as well as leveling a possible immune response from the body when used in vivo, various modification methods are used, such as nanocapsulation, the formation of enzymepolyelectrolyte complexes, immobilization of the enzyme on various functionalized carriers, etc. The chapter contains the information on examples of such biocatalysts, discussion of their advantages and disadvantages.
