Nano-: meaning, definitions and examples

Etymology

• The prefix 'nano-' comes from the Greek word 'nanos,' meaning dwarf, denoting very small size.
• 'Nano-' was first popularized in the 1970s as scientists began studying materials at the atomic level.
• The term 'nanotechnology' was introduced by K. Eric Drexler in his 1986 book 'Engines of Creation.'

Science

• Nanoparticles can be used in medicine to target specific cells, such as cancer cells, hoping to improve treatment outcomes.
• At the nanoscale, materials can exhibit different properties than at larger scales, leading to new inventions like stronger yet lighter materials.
• The behavior of materials at the nano level is governed by quantum effects, which can be very different from our everyday experiences.

Pop Culture

• Films such as 'Ant-Man' and 'Fantastic Voyage' explore ideas of shrinking people down to the nano scale, invoking interest in the concept.
• The rise of 'nano' in pop culture has led to numerous video games and comic books featuring miniaturized heroes and technology.

Technology

• Nanotechnology is being integrated into electronics, allowing devices to become smaller yet more powerful, such as in smartphone chips.
• Scientists are developing nanomaterials for better solar cells, hoping it will increase energy efficiency and lower costs.
• The latest innovations in drug delivery systems often include 'nano' technologies for more precise treatment at the cellular level.

Health

• Research is ongoing into using 'nano' medicines to improve how drugs are delivered directly to diseases, minimizing side effects.
• Some toothpaste now includes nanotechnology to help clean teeth more effectively and fight cavities.
• Nanoparticles can improve the detection of diseases through early diagnosis, often highlighted in ongoing health studies.
