No studies have examined the adsorption hetero-agglomeration and co-sedimentation of ENMs in the presence of a predator-prey interaction model of a real-world environmental situation Such an interaction model involving two organisms in lower trophic levels of the food chain can be represented by a bacterium and a ciliated protozoan E coli has been used extensively as a model bacterium in

agglomeration is a function of particle shape size surface area and their proximity to each other 27 The physiological and biological media commonly used in toxicity studies may affect their state of dispersion Therefore it is essential to measure the particle size distribution both "as-received" and "as-dosed " Protein coronas

Hypothesis As more sodium dodecylsulfate (SDS) monomers adsorb at the water/titanium dioxide (TiO 2) nanoparticles interface the particles become more stable against agglomeration and sediment more slowly SDS micelles are not expected to adsorb on the particles and affect the stability against agglomeration or sedimentation
