What are the Key Factors Influencing Nanotoxicity?
Several factors can influence the toxicity of nanomaterials used in catalysis:
Size: Smaller nanoparticles tend to have higher reactivity and can more easily penetrate biological membranes. Shape: The shape of nanoparticles can affect how they interact with cells and tissues. For example, rod-shaped nanoparticles may penetrate cells more easily than spherical ones. Surface Chemistry: Functional groups on the nanoparticle surface can interact with biological molecules, influencing toxicity. Aggregation State: Aggregated nanoparticles may exhibit different toxicological profiles compared to their dispersed counterparts.
