Safety is a primary concern when it comes to the application of nano coatings, especially in pediatric settings. Current research suggests that many nano coatings are safe for use around children when properly applied. However, it is crucial to conduct thorough toxicological studies to ensure that the nanoparticles do not pose a risk of toxicity or other adverse effects. Regulatory bodies like the FDA and EPA play essential roles in evaluating and approving these materials for medical and consumer use.
