The impact of contaminants on nanomaterials can be profound. Particulate contaminants can cause physical obstructions, leading to changes in surface area, reactivity, and other critical properties. Chemical contaminants can result in:
Surface Modification: Alteration of the surface chemistry of nanomaterials, affecting their interaction with other substances. Oxidation: Unwanted oxidation reactions that can degrade metal nanoparticles. Aggregation: Inducing aggregation of nanoparticles, which can lead to a loss of the unique properties that arise at the nanoscale.
