Description
Gold nanospheres are perhaps the most common form of gold nanoparticles. Other forms like nanostars, nanorods, and nanoflowers are also available.
Gold nanoparticles
Gold nanoparticles are widely used in the healthcare industry to produce lateral flow tests (tests that use immunochromatography to detect whether a target compound is present or absent in a sample). They’re used in pregnancy tests and COVID tests, for example. Such tests are quick and easy to use and are currently very popular.
Gold nanoparticles boast some particularly interesting optical properties. For example, optical signals can be enhanced by using surface plasmon resonance, an inherent phenomenon in gold nanoparticles. Gold nanoparticles are also used for their ability to boost signal intensity in Raman spectroscopy (Raman/SERS). They enhance the signal and greatly improve the readability of results. This in turn enables the early diagnosis of a number of diseases, such as cancer and neurodegenerative diseases.
The optical properties of gold nanospheres
Gold nanospheres typically exhibit a single surface plasmon resonance peak, with maximum absorption occurring in the red to infrared wavelength region, depending on their size.
Nanoparticles produced by SON boast impeccable characterisation and perfect reproducibility. This is particularly important with gold nanoparticles due to their optical properties.
Nanoparticle reproducibility is vital to ensuring consistent reactions. SON’s nanomaterials guarantee reproducible results and optimal performance.
