Nanotechnology

Nanotechnology, derived from the prefix “nano”, meaning one billionth, pertains to manipulating and utilizing matter at an incredibly minute scale, often at the level of individual atoms and molecules. Materials exhibit distinctive properties and behaviours at this miniature scale, revolutionizing various scientific and industrial domains.

Originating from theoretical physicist Richard Feynman’s visionary talk in 1959, wherein he proposed the ability to manipulate individual atoms, nanotechnology has evolved into a multidisciplinary field with vast implications across sectors. This technology operates within the nanometer range, between 1 and 100 nanometers, where the laws of classical physics yield quantum effects, enabling the creation of materials and devices with unprecedented functionalities.

Why is nanotechnology important?

We can use nanotechnology to create resources, devices and systems with sole properties and functions. The tiny size of the materials allows them to exhibit different bodily and chemical properties than similar materials on a larger scale. Due to their small size, nanomaterials have a large surface-to-volume ratio, which can lead to higher reactivity, strength, and conductivity.

Additionally, the small size of nanomaterials allows them to be easily incorporated into a wide variety of products and processes, including electronic devices, medical treatments, energy production, and environmental remediation. The properties of nanomaterials also make them useful for creating new products and improving existing ones, for example, by increasing the efficiency of solar cells and batteries, creating more robust and more durable building materials, and developing more effective medical treatments.
