25nm Nanorod UVVIS

Nanopartz™ Gold Nanoparticles for Zero Order Diagnostics

Nanopartz™ Gold Nanoparticles for zero order diagnostics utilize the complete line of nanospheres and nanorods for SPR shifting from 500nm to the near IR. These particles are covalently conjugated to short length linkers to optimize the SPR shift of the particle in response to a conjugation. Every batch is completely characterized including size, monodispersity, aggregation, residual chemicals, and concentration. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. This product comes in two concentrations, 2.5mg/mL and 12.5mg/mL. The highly concentrated gold nanoparticles come in a range of conjugations.

DLS (Malvern Nano ZS) for zeta potential measurement

ICP-MS (Varian 820-MS) for gold mass measurements

TEM (Phillips CM-100 100KV) for sizing

These gold nanoparticles exhibit extinctions from 500nm to 1064nm, perfect for use in UV-VIS analytical systems. These gold nanoparticles come with a very short length covalent conjugation, specifically suited for zero order diagnostics as it is a well known property that the extinction of gold nanoparticles is very sensitive to the local index of refraction. The covalent attachment ensures minimal non specific binding. The customer has a choice for radiation sterilization (no sodium azide is used), certification and endotoxin free products.

How sensitive is the product?

That depends on a number of factors including the size and shape of the gold nanoparticle and the size of the target protein. In general, nanorods are more sensitive than spheres (shifts in aspect ratio result in a greater SPR change than a change in diameter for spheres), and larger particles are more sensitive than smaller ones. Also, a system targeting larger proteins will be more sensitive than one targeting smaller proteins.

Another very important variable is whether the system is a homogeneous or heterogeneous system. In general, a homogeneous system will measure many particles simultaneously (normally through a path length). A heterogenous system can be designed to look at individual, fixed gold nanoparticles on a slide (for example). Consequently, the fact that single particle statistics are more sensitive than bulk particle statistics, a heterogeneous system will be more sensitive.

Given these parameters, publications have shown attomolar detection for nanorods using a biotin/streptavidin system in a heterogenous system on a glass slide. A good example of this is shown in Nucz et al. "Label-Free Plasmonic Detection of Biomolecular Binding by a Single Gold Nanorod" http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3003601/ .

"We have looked at many different gold nanoparticles samples from Nanopartz including spheres, rods, and microrods using single particle spectroscopy techniques and are extremely happy with the quality of the samples and the service provided by Nanopartz."
