Are there specific nanoparticles that are more hazardous?
Yes, certain nanoparticles are considered more hazardous than others. For instance, carbon nanotubes have been compared to asbestos in terms of their potential to cause lung disease. Silver nanoparticles, commonly used for their antimicrobial properties, can be toxic to aquatic life. The toxicity often depends on factors such as particle size, surface area, and chemical composition.
