Nanoengineering is the study and application of engineering principles at the nanoscale level. This interdisciplinary field focuses on developing novel devices and materials that can revolutionize medicine, electronics, energy, and environmental science. Synonyms for nanoengineering can include nanotechnology, nanoscience, molecular engineering, nanofabrication, and nanomanufacturing. All these terms refer to the same general idea of manipulating materials at the smallest possible scale. They have enabled the creation of ultra-small devices such as nanorobots, sensors, and drug delivery systems. As this field continues to grow, it is expected that more innovative tools and solutions will emerge, advancing our understanding and ability to engineer at the nanoscale.
