It is really interested to have the evidence that the organic phosphorus, especially phosphate esters, are closely related to the nanoparticles which is small than 10 nm with the high concentration of iron. I am wondering if these nanoparticles is related to iron oxide.

My recently work about the phosphate ester and iron oxide nanoparticles -in the laboratory-have confirmed that these inorganic iron oxide nanoparticles have the catalysis effect on the hydrolysis of phosphate ester. If we can demonstrated, it further support the idea of inorganic enzyme and these enzyme are still play the role from the view of phosphorus biogeochemistry.

Please read my work, any comments are welcome
