However, it wasn’t until the 1980s that nanotechnology started to gain significant attention in the scientific community.
In 1986, the concept of the scanning tunneling microscope was introduced, which allowed researchers to visualize and manipulate individual atoms and molecules. This breakthrough technology provided the foundation for the development of nanotechnology, and it marked the beginning of a new era in the study of materials science.
Throughout the 1990s, the field of nanotechnology continued to grow rapidly, and several key milestones were achieved. In 1991, the first carbon nanotubes were discovered by Japanese physicist Sumio Iijima, and they quickly became one of the most studied and promising nanomaterials due to their unique properties.
Another significant breakthrough came in 1997 when Eric Drexler published his book “Nanosystems: Molecular Machinery, Manufacturing, and Computation,” in which he proposed the idea of nanorobots, tiny machines that could perform complex tasks at the nanoscale level. While the concept of nanorobots is still in the experimental stage, it has the potential to revolutionize many industries, including medicine and manufacturing.
In the early 2000s, the development of nanotechnology continued to accelerate, and several new materials and technologies were introduced. In 2004, Andre Geim and Konstantin Novoselov discovered graphene, a two-dimensional material made of carbon atoms that is incredibly strong, lightweight, and conductive. Graphene has the potential to revolutionize many industries, including electronics, energy, and medicine.
