A wide range of
organophosphorus compounds are used for their toxicity as pesticides (herbicides, insecticides, fungicides, etc.) and weaponised as nerve agents against enemy humans.
In this study, the authors reported having «functionalized» the silica pores by lining them with
compounds that varied depending on the enzyme to be ensnared — amine and carboxyl groups carrying charges opposite that of three common, off - the - shelf biocatalysts: glucose oxidase (GOX), glucose isomerase (GI) and
organophosphorus hydrolase (OPH).
