These highly monodisperse gold nanoparticles are supplied with surface capping suitable for organic solvents. With appropriate drying they can be used to create self-assemblies, such as those used in printed electronics.
Gold nanoparticles are commonly used due to their size dependent surface plasmon resonances. Typically used in bioseparation or biosensors, the absorption peaks can be tracked with small changes in the environment. Unfortunately many gold nanoparticles developed for organic solvents use thiol capping agents, which limit their application. These particles have a surface-capping of long-chain hydrophobic amines, where the exchange of these molecules can be more easily tailored for a desired application.
