Several scientists have made significant contributions to the advancement of nanotechnology. For instance, Sumio Iijima discovered carbon nanotubes in 1991, a breakthrough that opened new avenues for material science. Additionally, Chad Mirkin developed the Dip-Pen Nanolithography technique, which has applications in creating nanoscale patterns and structures. The Nobel Prize-winning work of Andre Geim and Konstantin Novoselov on graphene has also had a monumental impact, revealing the extraordinary properties of this one-atom-thick material.
