The toxicity of nanoparticles can be pH-dependent. In acidic or basic environments, the surface chemistry of nanoparticles may change, influencing their interaction with biological systems. For instance, in acidic conditions, certain nanoparticles may dissolve and release toxic ions, while in neutral conditions, they might be more stable and less toxic. Understanding these interactions is vital for assessing the safety of nanomaterials in biomedical and environmental applications.
