Nanorods are tiny, rod-shaped structures that typically range from 1 to 100 nanometers in diameter and can be several hundred nanometers long. They are made from various materials, including metals like gold and silver, as well as semiconductors like cadmium selenide. Due to their unique shape and size, nanorods exhibit special optical, electrical, and thermal properties that differ from their bulk counterparts. These properties make nanorods useful in various applications, such as in medicine for targeted drug delivery and imaging, and in electronics for developing advanced components. Researchers are also exploring their potential in solar energy conversion and sensors, highlighting their versatility in modern technology.
