Particulate contaminants refer to solid or liquid particles that can be suspended in the air or other environments. These contaminants can include dust, smoke, and various nanoparticles. In the context of nanotechnology, particulate contaminants often refer to nanoscale materials that can interfere with the desired functionality of a nanostructure or system. Chemical contaminants, on the other hand, are unwanted chemical substances that can be either organic or inorganic. These can interact with nanomaterials in ways that might degrade their properties or lead to unwanted reactions.
