What are the potential side effects of nanotechnology?
The potential side effects of nanotechnology include but are not limited to, toxicity, environmental impact, and unforeseen interactions with biological systems. The very properties that make nanoparticles useful—such as their small size and high reactivity—can also make them potentially harmful. For instance, nanoparticles can easily penetrate cells and tissues, which might lead to cellular damage or even trigger immune responses.
