The primary safety concerns in nanotechnology revolve around the potential toxicity of nanoparticles. Due to their small size, nanoparticles can easily enter biological systems and interact with cells, proteins, and DNA in ways that larger particles cannot. This can lead to cytotoxicity, genotoxicity, and other adverse effects. Additional concerns include the environmental impact of nanoparticles, particularly their persistence and bioaccumulation in ecosystems.
