Citrate stabilized nanoparticles have a surface that is readily displaced by other biomolecules or polymers and is the capping agent of choice when using physisorption (noncovalent interactions such as van der Waals forces) to further modify the nanoparticle surface. Citrate capped particles are suspended in 2mM citrate buffer, pH 7.4. (Available soon).
Tannic acid is a multidentate capping agent that can be displaced with many thiol containing ligands. As a general rule, tannic acid coated nanoparticles are more stable at high particle concentrations, while citrate capped nanoparticles are more stable in higher ionic strength solutions. Tannic acid capped particles are suspended in water.
The PELCO® NanoXact and BioPure gold colloids (nanoparticles) are extensively characterized (see Technical Data below) and designed to meet the rigorous research demands in today’s market. They range in size from 5 to 100nm with 15 different sizes to choose from. The gold colloids come with comprehensive specification sheets that provide all of the physical and optical characterization data necessary to integrate the nanoparticles into Surface Enhanced Raman Spectroscopy (SERS), plasmonic and photonic applications. Product Description
Stability and StorageThe PELCO® NanoXact and BioPure gold colloids should be stored at 4°C.
Product testing indicates increased stability can be attained by following the storage recommendations. |
