Nanoscience is the study of the sometimes strange world of the infinitely small – the atoms and sub-atomic particles that go to make up all matter in the universe. To give an idea of the scales nanoscientists work with, think of the width of a human hair, which is 100,000 nanometres thick. So, a single nanometre is as if you take the width of one human hair, and divide it into 100,000 slices. Nanoscientists study and seek to exploit the weird and wonderful properties of substances on this scale to create new types of materials to make extraordinary advances in materials science such as laptop screens you could roll up or a mobile phone that never needs to be charged or materials that can withstand a rocket’s re-entry to earth.

What the job involves

  • Research and lab experiments
  • Conduct peer reviewed research
  • In medicine, nanoscientists conduct experiments, for instance making tissue repairs at the cellular level
  • Design experiments to use nano-sized particles, devices, and perhaps someday robots to repair the human body
  • In the food sector, nanotechnology is used to identify any potential diseases or other contaminants
  • Conduct research to find ways to use nanotechnology to keep food fresher for longer
  • In engineering, research to design ever-smaller components on microchips with greater electrical resistance or conductivity to vastly improve performance and “brain” power
  • Research and develop nanofibres to create lightweight, super-strong materials for a range of uses
  • Research and develop minute sensors that can remotely detect trace amounts of dangerous chemicals or radiation

How your career can develop

Prospects are huge for those who work and study and probe into the world of the infinitely tiny. Qualified and experienced scientists often specialise in either the industrial or engineering fields or pure research or medical nanotechnology. They often move on to nano techniques and instrumentation, nanomaterials, nanotechnology in manufacturing, microbiology and nano fabrication. Postgraduate study to doctorate level is common and is essential for medical nanoscience.

Why nanoscience matters

To give you an idea of the unbelievably small dimensions with which nanoscientists work, the average page of printed A4 paper is approximately 57,000 nanometers thick.
