Nanorod - Wikipedia
Gold nanorods under electron microscopy. In nanotechnology, nanorods are one morphology of nanoscale objects. Each of their dimensions range from 1–100 nm. They may be synthesized from metals or semiconducting materials. [1] Standard aspect ratios (length divided by width) are 3-5. Nanorods are produced by direct chemical synthesis.
Nanorod - an overview | ScienceDirect Topics
Nanorods are two-dimensional nanomaterials that are fabricated by semiconducting materials or metals. One common method of nanorod synthesis is the chemical method. In chemical synthesis, shape control chemicals are used to grow elongated rods at different rates. In biological sensing, cold nanorods are good candidates.
Nanorods: Elongated Nanostructures with Unique Properties
Nanorods are elongated nanostructures with a diameter in the nanometer range and an aspect ratio (length-to-width ratio) greater than one. They are typically characterized by their unique optical, electrical, and magnetic properties that arise from their anisotropic shape and quantum confinement effects.

Nanorod - an overview | ScienceDirect Topics
Nanorods are nanostructures with an elongated shape, characterized by a length-to-width ratio between 3 and 6. Unlike spherical nanoparticles, nanorods exhibit two distinct plasmon resonances - a longitudinal mode corresponding to oscillations along the length and a transverse mode corresponding to oscillations along the width.
Nanorod - an overview | ScienceDirect Topics
Nanorods are rods, pillars, or columns with a lateral dimension on the order of tens of nanometers. Their aspect ratio is typically on the order of 10 or smaller; if the aspect ratio is larger, they are generally called nanowires.
Figure 1 shows different examples of nanorods and nanowires made in different materials. The first three categories are considered a bottom-up approach while lithography is a top-down approach.
