Abstract
The ability to routinely and accurately measure the physical and chemical properties of synthetic nanoparticles is crucial for risk assessment. Non-equilibrium system-dependent behaviours and unique characteristics of tailored nanomaterials make traditional characterization difficult. Scientists are developing and refining new methods to overcome these issues. This chapter assesses proven and verified methods for assessing nanomaterial health and safety hazards. Nanomaterials are examined for dustiness, zeta potential, agglomeration rate, surface affinity, dissolution rate, solubility, and reactive oxygen species generation. Validation and repeatability are worse for extrinsic property characterization than intrinsic. When evaluating how media qualities may affect the result, this is true. Meta-data is needed to compare extrinsic property findings across studies. Even though some of these processes have been standardized and automated, the factors affecting evaluation reliability and repeatability are still unknown.
