Nanorobots

Definition

Nanorobots are tiny machines built at the nanoscale, typically ranging from 1 to 100 nanometers in size, designed to perform specific tasks at the molecular or cellular level. These miniature devices hold immense potential in medicine, particularly in targeted therapies where they can deliver drugs directly to diseased cells or tissues while minimizing side effects on healthy cells.
