Nanorods are elongated nanostructures with diameters on the order of a few nanometers and lengths typically ranging from tens to hundreds of nanometers. They exhibit unique physical and chemical properties due to their high aspect ratio, and have numerous potential applications in various fields such as electronics, photonics, catalysis, and biomedicine. Research on nanorods focuses on the synthesis and characterization of these nanostructures, as well as exploring their properties and applications. Various methods are used to fabricate nanorods, including template-assisted growth, chemical vapor deposition, and solution-phase methods. Characterization techniques such as transmission electron microscopy, scanning electron microscopy, and spectroscopy are utilized to study the morphology, structure, and optical properties of nanorods. In terms of applications, nanorods show promise in fields such as sensing, imaging, drug delivery, and energy storage. Their tunable optical and electronic properties make them attractive for use in photovoltaic devices, light-emitting diodes, and sensors. Additionally, the biocompatibility and high surface area of nanorods make them ideal candidates for drug delivery systems and bioimaging agents. Overall, research on nanorods continues to advance our understanding of these unique nanostructures and their potential applications in various technological and biomedical fields.
