Nanoscience is the study of materials and structures at the nanoscale, which is about 1 to 100 nanometers in size. At this tiny scale, the properties of materials can change significantly compared to their larger counterparts. This field combines aspects of physics, chemistry, and biology to explore how these small structures can be manipulated and utilized in various applications. Researchers in nanoscience investigate how nanoparticles, such as carbon nanotubes and quantum dots, can be used in fields like medicine, electronics, and energy. For example, nanotechnology can improve drug delivery systems or enhance the efficiency of solar cells. Understanding these nanoscale phenomena opens up new possibilities for innovation and technology.
