Properties of Nanomaterials


  • Nanotechnology involves manipulating substances at the nanoscale (1 to 100 nanometres) to take advantage of their enhanced properties at this size.

Enhanced Physical Properties

  • Strength: Materials at the nanoscale often have greater strength per unit of mass compared to their macro-scale equivalents, making them ideal for lightweight structural applications.
  • Electrical conductivity: Some nanomaterials exhibit increased electric conductivity, important in miniature electronics.
  • Reactivity: Nanoscale materials generally have a larger surface area to volume ratio compared to larger particles, leading to increased reactivity.

Improved Chemical Properties

  • Chemical reactivity: Due to their increased surface area, nanomaterials often have enhanced chemical reactivity, potentially increasing their efficiency as catalysts.
  • Controlled release: Some nanomaterials can encapsulate substances and release them in a controlled manner, a property utilised in drug delivery systems.

Advantages in Medicine

  • Drug delivery: Nanotechnology can enhance drug delivery, as nanoparticles can be engineered to target specific cells, such as cancer cells, reducing the impact on healthy cells.
  • Diagnostics: Nanosensors can detect diseases at very early stages with high accuracy.

Environmental Benefits

  • Energy efficiency: Nanotechnology can improve the efficiency of fuel production and energy storage systems.
  • Pollution control: Nanomaterials can be employed in environmental clean-up applications due to their high reactivity and ability to bind to specific pollutants.

Advancements in Electronics

  • Miniaturization: Nanotechnology allows for the development of smaller, more efficient electronic devices.
  • Improved performance: Nanoscale components can often operate faster and use less energy than larger components.


  • In various fields, the unique properties of nanomaterials offer several advantages over traditional materials. However, the potential risks and impacts on health and the environment need to be carefully studied and addressed.
