introduction
The gold nanorod is a rod-shaped gold nanoparticle that has a potential response in the fields of biological detection, biological imaging, disease diagnosis and treatment.
With value. According to the technical report issued by the International Organization for Standardization Nanotechnology Committee ISO /T R13014..2012 "Nanotechnology Project
Guidance on Physical and Chemical Parameter Characterization of Toxicity Evaluation of Nanomaterials ", which involves key physicochemical parameters including size and size distribution, agglomeration/aggregation
State, shape, surface area/specific surface area, composition, purity, surface chemistry, surface charge, solubility/dispersibility. This standard is consistent with its reunion/poly
Set the state corresponding.
The nanoparticle aggregates are aggregates formed by the aggregation of two or more nanoparticles together. So it is used to characterize the particle size
Methods, such as light scattering, microscopic imaging techniques, can be used for the characterization of aggregate structures. For gold with a surface plasmon resonance characteristic
Is a nanostructure, and the agglomerated state has a significant effect on this resonance characteristic, so it is also possible to characterize the agglomeration state according to its variation. At present domestic
The relevant standards have not yet been promulgated. This standard is based on extinction spectroscopy to characterize the structure of gold nanorod aggregates.
Characterization of Aggregate Structure of Gold Nanometer Rod by Extinction Spectroscopy
1 Scope
This standard specifies a method for characterizing the structure of gold nanorod aggregates based on extinction spectroscopy.
This standard applies to extinction spectroscopy to characterize the structure of gold nanorod aggregates, and other noble metal nanoclusters can also be used as reference.
