HI-6-loaded PEGylated liposomes: an on-site first-aid strategy for acute organophosphorus agent poisoning.

Organophosphorus agents, also known as nerve agents, are very dangerous chemicals that were used as chemical warfare agents. HI-6 is one of the most promising reactivators which is effective in reactivating AChE inhibited by many nerve agents. However, the fast in-vivo clearance of HI-6 became a large barrier for first aid use under some sophisticated circumstances.
