Nanotechnology is a fascinating field that operates at the atomic or molecular scale, allowing scientists and engineers to manipulate matter in ways that were once unimaginable. Nanotechnology involves engineering materials and structures at the nanoscale, which typically ranges from 1 to 100 nanometers (nm). The term “nano” comes from the Greek word “Nanos,” meaning “dwarf” or something extremely small. To put it in perspective: “A nanometer (nm) is one billionth of a meter”. Nanotechnology enables us to design novel structures, materials, and devices that thrive at these tiny dimensions.
Why Is Nanoscale Relevant in today’s era?
In the 20th century, researchers discovered that materials with at least one facet in the 1 to 100 nm range exhibit distinct physical and chemical properties compared to the same materials at larger scales. For example, consider silver: When broken down into smaller proportions, each piece retains basic properties like density, texture, and boiling point. However, these properties change at the nanoscale based on size, shape, and composition. Nanoscale materials open up new possibilities in fields such as medicine, manufacturing, energy, and materials science.
