Nanotechnology is being used to make special food packaging that keeps food fresh longer by stopping it from going bad. Scientists are using tiny particles to create packaging that can prevent foods from getting spoiled. This new technology can help make our food healthier and last longer. By adding these tiny particles to packaging, foods like meat, seafood, fruits, and vegetables can stay fresh for a longer time. However, more work is needed to make sure this technology is safe, affordable, and can be used on a large scale before it can be widely used.
