Nanos are extremely small particles or structures that typically range from 1 to 100 nanometers in size. A nanometer is one-billionth of a meter, making nanos significantly smaller than most cells and even molecules. Due to their tiny size, nanos exhibit unique physical and chemical properties that differ from their larger counterparts, which can lead to innovative applications in various fields. In technology and medicine, nanos are used in areas such as nanotechnology, drug delivery, and materials science. For example, nanos can enhance the effectiveness of medications by allowing for targeted delivery to specific cells. Additionally, nanos are utilized in creating stronger and lighter materials, contributing to advancements in electronics and energy storage.
