A self-degradable hydrogel sensor for a nerve agent tabun surrogate through a self-propagating cascade [PDF]

open access: goldCell Reports Physical Science, 2021
Summary: Nerve agents that irreversibly deactivate the enzyme acetylcholinesterase are extremely toxic weapons of mass destruction. Thus, developing methods to detect these lethal agents is important.
