Nanorods

Nanorods

Nanorods are produced by direct chemical synthesis. They may be synthesized from metals or semiconducting materials.Aggregated diamond nanorods (ADNR) or hyperdiamonds are a nanocrystalline form of diamond and also they are hardest and least compressible known material. They have a modulus of 491 gigapascals (GPa), while a conventional diamond has a modulus of 442 GPa.

ADNRs are also 0.3% denser than regular diamond.Gold nanorods have minimal inherent cytotoxicity and used in biomedical applications. Coated gold nanorods have long circulation times of several hours in-vivo.
