Nano-Intercalated Organophosphorus-Hydrolyzing Enzymes in Organophosphorus Antagonism [PDF]

AAPS PharmSciTech, 2011
A dendritic poly(2-alkyloxazoline)-based polymer was studied as a new carrier system for the organophosphorus-hydrolyzing recombinant enzymes, organophosphorus acid anhydrolase and organophosphorus hydrolase. Paraoxon (PO) and diisopropylfluorophosphate (DFP) were used as model organophosphorus compounds.
