Carboxyl Silver Nanoparticles

Home 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.


  • 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.


  • Ideal for development of silver conjugates for use in for example: 
  • Immunoblotting 
  • Lateral Flow Assays 
  • LSPR Assays 
  • Microscopy Applications (e.g. TEM, Darkfield)
