Nanoscience is well on its way to establishing itself as one of the critical technologies of the 21st Century. Just as semiconductors gave rise to computers, smart phones, the Internet, medical devices, and an endless stream of consumer products, nanoscience is enabling the development of new technologies in fields as diverse as electronics, medicine, photonics, energy, and quantum physics. Nanoscale constructions provide this flexibility for two reasons. First, they are small and precise enough to interact with molecules in entirely new ways. Nanomedicines, for example, often encapsulate drugs in molecular packages decorated with segments of molecules that enable them to target specific organs and diseases, and, once there, convince those cells to ingest the medication. Metal-organic frameworks, complex molecules engineered to reduce energy use in chemical reactions and capture carbon emissions from combustion, are another example. Second, and more intriguingly, nanoscale devices are closer in size to electrons and photons, and may interact with them in ways that are fundamentally different from the behavior of larger objects. For example, metamaterials, arrays of nanoscale structures, can bend light around an object to make it appear invisible. Nanoscale electronics can exploit quantum phenomena, like electron spin, energy waves, and quantum states to capture, store, and process information. As these technologies and other emerging applications reach commercialization, they are certain to change nearly every sphere of life.
