Gold Nanoparticle Products
Cytodiagnostics spherical and non-spherical gold nanoparticles are made with unique proprietary protocols resulting in particles with uniform shapes and a narrow size distributions. In addition, by modifying the gold nanoparticle surface, we offer multifunctional nanoparticles such as fluorescent gold nanoparticles, antibody gold conjugates, biotin, carboxyl, amine and methyl functionalized particles.

Standard Gold Nanoparticles
For standard applications such as protein and ligand adsorption to the gold surface.
Features
- Superior size distribution and shape compared to the leading competitor.
- Ideal for development of gold conjugates.
Reactant Free Gold Nanoparticles
For sensitive applications requiring a minimum amount of residual reactants.
Features
- Less than 1% of reactants remaining
- Ideal for sensitive applications.
Stabilized Gold Nanoparticles
For thiolated ligand adsorption and other non-traditional applications requiring harsher conditions.
Features
- Increased stability to salt
- Ideal for adsorption of thiolated ligands
PEGylated Gold Nanorods
Monodisperse and shape uniform PEGylated gold nanorods with methyl, carboxyl or amine functional groups.
Features
- Absorption in the far-red to near-infrared part of the spectrum.
- Provides an alternative particle shape to standard spherical gold nanoparticles.
Gold NanoUrchins
Unique spherical gold nanoparticles with spiky protrusions. A great alternative to our standard spherical gold nanoparticles if absorption is desired in the far-red while maintaining a small particle size.
Features
- Near spherical particles with small diameters but with absorption in the far-red.
- Readily adsorbs thiolated-ligands and proteins to its surface.
Functionalized Gold Nanoparticles
Functionalized and pegylated gold nanoparticles for applications such as conjugation of proteins using EDC/NHS coupling chemistry.
Featured Category - Biotin Gold Nanoparticles
Gold nanoparticles functionalized with biotin for binding and detection of streptavidin conjugated samples.
Available in sizes from 5nm to 100nm.
Gold Nanoparticle Conjugates
High quality gold nanoparticle conjugates for immunoblotting, light microscopy and electron microscopy applications.
Categories
Featured Application - Immunogold Dot-Blot
Mouse IgG (H+L) was spotted onto a PVDF membrane according to the amounts indicated in the figure and probed with Cytodiagnostics 15nm anti-mouse IgG (H+L) gold conjugate.
Detection was subsequently enhanced using Cytodiagnostics silver enhancement kit for membranes.
Fluorescent Gold Nanoparticles
Fluorescently labeled gold nanoparticles for optical and electron microscopy applications.
Featured Product - 60nm Cyto 750 Labeled Gold Nanoparticles
Our Cyto 750 fluorescently labeled gold nanoparticles are ideal for in vivo applications such as passive tumor targeting and imaging.
Due to emission of the dye in the near-infrared (NIR), background noise from biological tissues is reduced offering higher sensitivity in your assay.
Size Optimization Panels
Combinations of different sized non-functionalized and functionalized gold nanoparticle products. Ideal for determining optimal gold nanoparticle size in your application.
Features
- Optimally combined sizes to suit your particular application
- Convenient small volume formats
Conjugation Kits
Kits to optimize protein adsorption to Cytodiagnostics standard
gold nanoparticles.
Features
- Complete system with gold nanoparticles and buffers
- Detailed conjugation optimization protocols
Protein Conjugation
