S. noTechniquesApplications in environmental nanotoxicology assessment

1Dynamic light scatteringGives an idea of the particle sizes in the whole dispersion
2Differential centrifugal sedimentationTo generate fractions containing different particle sizes
3Size exclusion chromatographyChromatographic fractions are generated according to molecular weight, enabling plots of size distribution
4Field flow fractionation techniqueHigh-resolution particle size distributions and separation of subfractions
5Electrophoretic mobilityTo determine the surface properties of nanoparticles that is net surface charge
6N2 absorption (BET analysis)For measuring the specific surface area of particles
7GravimetryTo filter the environmental samples
8TurbidimetryParticle concentration can be estimated
