Proteins limit nanoparticle dispersal: sulfate-reducing bacteria
Extracellular proteins of some sulfate-reducing bacteria limit the dispersal of nanoparticles by aggregating them.

It is unclear whether the proteins, amino acids, and polypeptides are released into the environment when the bacteria die and are scavenged by hydrophobic zinc sulfide surfaces, or whether the bacteria export them while alive.
