Carboxyl Silver Nanoparticles
Carboxyl functionalized silver nanoparticles are ideal for conjugation of proteins and other primary amine containing ligands using standard EDC/NHS coupling chemistry.
Our carboxylated silver nanoparticles are available in 8 different sizes ranging from 10-100nm, are more than 95% spherical and have uniform size distribution (CV <18%). In addition, the choice of two different length PEG surface spacer allows control of the distance between a conjugated molecule and the silver surface.
Features
- Superior size distribution compared to the leading competitor; available from 10nm to 100nm.
- Precisely engineered surface with an optimized carboxyl group density for easy conjugation.
Applications
- Ideal for development of silver conjugates for use in for example:
- Immunoblotting
- Lateral Flow Assays
- LSPR Assays
- Microscopy Applications (e.g. TEM, Darkfield)

Properties
The carboxyl functionalized silver nanoparticle surface allows for covalent conjugation of antibodies, proteins and other ligands using standard EDC/NHS coupling chemistry.
The precisely engineered silver nanoparticle surface with extended carboxyl groups maximizes conjugation efficiency by minimizing steric hindrance while still maintaining low non-specific protein binding. These features results in reliable and reproducible conjugates.
