Exciting new nanotechnology-based medicines are now in clinical trials, which may be available soon to treat patients. Some use nanoparticles to deliver toxic anti-cancer drugs targeted directly to tumors, minimizing drug damage to other parts of the body. Others help medical imaging tools, like MRIs and CAT scans, work better and more safely. Nanotechnology is helping scientists make our homes, cars, and businesses more energy-efficient through new fuel cells, batteries, and solar panels. It is also helping to find ways to purify drinking water and to detect and clean up environmental waste and damage.
Nanomaterials are being tested for use in food packaging to greatly improve shelf life and safety. Nanosensors to detect food-borne pathogens are also being developed for food packaging. New nanomaterials will be stronger, lighter, and more durable than the materials we use today in buildings, bridges, automobiles, and more. Scientists have experimented with nanomaterials that bend light in unique ways that may enable the development of an “invisibility cloak.” The possibilities seem limitless, and the future of nanotechnology holds great potential.
