What Are the Key Factors Influencing Nanomaterial Toxicity?
Several factors can influence the toxicity of nanomaterials:
1. Size and shape: Smaller nanoparticles can easily penetrate cells and tissues, potentially leading to higher toxicity. 2. Surface chemistry: The presence of functional groups on the surface of nanoparticles can affect their interaction with biological systems. 3. Dosage and exposure time: Higher doses and prolonged exposure can increase the risk of adverse effects. 4. Aggregation state: Nanoparticles can aggregate, altering their properties and potentially reducing or enhancing their toxicity.
