Nanospheres are tiny spherical particles that typically range in size from 1 to 100 nanometers. They can be made from various materials, including metals, polymers, and silica. Due to their small size, they have unique physical and chemical properties, making them useful in fields like medicine, electronics, and materials science. In medicine, nanospheres can be used for targeted drug delivery, allowing medications to be delivered directly to specific cells or tissues. In electronics, they can enhance the performance of devices by improving conductivity or enabling new functionalities. Their versatility makes them a significant area of research and development.
