Description

technical field

[0001] The invention discloses an eight-branched gold nanoparticle, a preparation method, an application and an intermediate thereof. Background technique

[0002] At the nanoscale, metals exhibit distinctive and excellent properties that make them outstanding in a wide range of research applications. Among them, gold nanoparticles have the characteristics of good biological inertness and easy surface modification, making them widely studied in the biological field. Like other nanomaterials, the size and shape of gold nanoparticles are two crucial parameters, which are used to tune the properties of the particles to meet different applications. In most cases, particles with different configurations have different physicochemical properties, so the morphology parameter is more general in adjusting particle properties.

[0003] Branch-like gold nanoparticles have high specific surface area, tip electromagnetic field enhancement, unique surface plasmon resonan...
