Nanotechnology, the manipulation of matter on a molecular scale, is all around us in our everyday lives. Chocolate, non-dairy creamer, and sunscreen are examples of consumer products with a high content of nanoparticles. Nanotechnology holds great potential for environmental applications like wastewater treatment and nanobionic engineering of plants. Due to their unique and adaptable properties for targeted therapeutic payload delivery, nanoparticles are also emerging as promising tools for innovative pharmaceutical treatment. Nevertheless, licensing regulations specifically for nanomaterials are lacking, and the long-term effects of nanoparticles on both the environment and human health need to be further clarified.
