What if by using microscopic robots 100,000 times thinner than a human hair we could seeks out and eliminate disease, illness and injuries? It may sound crazy, but with the invention of nanotechnology, it's becoming more and more possible. Nanotechnology—or manipulating matter at the molecular level (one billionth of a meter)—has the power to take science to yet unseen heights. For example, the world's dependency on oil may dwindle with advanced projects researchers are working on to create solar cells five times more efficient than regular silicon particles found in fossil fuels. Nanorobots are often utilized by the scientific community for their atomic size and ability to assist doctors-in-training in tracking bodily processes, for scientists to better facilitate medical testing and even to potentially repair injured DNA. Tiny magnets known as nanomagnets can attach themselves to metallic particles and pollutants in water—such as 99 percent of deadly arsenic—helping to better conserve and recycle stressed resources while making drinking water cleaner and safer.
The concept of nanotechnology may seem unreal, but its application and potential are unlimited when it comes to the advancement of science. These microscopic vessels, be they magnets or robots, are opening more and more doors for scientific breakthroughs that benefit people worldwide. From treatment for disease, to a decrease on foreign oil, to conserving the Earth's natural resources: nanotechnology is the future—and it's likely here to stay.
