The health effects of nanotechnology are still not fully understood, but there are concerns about the potential risks. Nanoparticles can enter the human body through inhalation, ingestion, or skin contact. Once inside, they can cross biological barriers and reach vital organs, potentially causing inflammation, oxidative stress, and even DNA damage. While some nanomaterials are being developed for medical applications, such as drug delivery systems, their long-term effects on human health need to be thoroughly studied. Regulatory agencies must establish guidelines for the safe use of nanotechnology to minimize potential health risks.
