Nanotechnology And Safety Protocols

Key Concepts and Definitions

Nanotechnology involves the manipulation of materials at the nanoscale, typically between 1 and 100 nanometers. At this scale, materials exhibit unique properties—such as increased strength, lighter weight, and enhanced chemical reactivity—that differ significantly from their macroscopic counterparts. Key concepts include:

• Nanomaterials: Substances engineered at the nanoscale, including nanoparticles, nanowires, and nanotubes.
• Self-assembly: The process by which molecules organize themselves into structured arrangements without external guidance.
• Quantum effects: Phenomena that emerge at the nanoscale, influencing electrical, optical, and magnetic properties.

Historical Milestones in Nanotechnology

Nanotechnology's roots trace back to Richard Feynman's 1959 lecture, "There's Plenty of Room at the Bottom," which envisioned manipulating atoms directly. Key milestones include:

• 1981: The invention of the scanning tunneling microscope (STM), enabling visualization of individual atoms.
• 1991: Discovery of carbon nanotubes by Sumio Iijima, sparking interest in nanomaterials.
