Nanotechnologists work with materials and devices at the nanoscale to develop new technologies that have applications across a wide range of industries, from medicine to energy to electronics. They design and manipulate nanostructures to enhance the properties of materials and create new products that were previously impossible at a larger scale. Nanotechnologists are involved in research, testing, and development of nanomaterials, including carbon nanotubes, nanoparticles, and nanocomposites. A background in materials science, chemistry, or physics is often required, and many hold a graduate degree. They play a crucial role in advancing technological capabilities and improving products across various industries.
