Functional Fate Groups: Environmentally-transformed ENMs

NanoFASE Functional Fate groupings describe the transformed version of the NM following incubation in the specific environmental compartment, whilst also reflecting the initial NM core chemistry and whether any coating / capping / stabilizer has been retained or lost.  

Where data are available, the groupings also include details of any acquired biomolecule corona, change in surface speciation, etc.

Some transformations that can occur in the environment.
