Citrate Gold Nanoparticles (AuNPs)
Citrate Gold Nanoparticles are capped with citrate ions, which confer colloidal stability and a weakly bound surface layer. This allows for electrostatic adsorption of biomolecules and facilitates downstream functionalization.
Applications:
- Adsorption-based conjugation of proteins, DNA, or peptides
- Fabrication of biosensors and diagnostic devices
- Nanomaterial research and nanoparticle modification studies
The particles are optically tunable, size-controlled, and suitable for a wide range of laboratory applications.
