PELCO® NanoXact™
Gold and Silica Shell Gold Colloid

Nanoparticles Developed for Ted Pella, Inc.

The PELCO® NanoXact™ 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 20 to 100nm.

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

  • Capped/stabilized with PVP or Silica Shells
  • Characterized by UVVIS, TEM, DLS and zeta potential. Residual reactants have been removed.
  • PELCO® NanoXact™ gold colloids are available dried and coated with PVP (polyvinylpyrrolidone) in 1 or 5mg
  • PELCO® NanoXact™ also available with 20nm silica shells, zeta potential -10 to -55mV in ethanol and 20nm aminated silica shells, zeta potential +10 to +50mV in ethanol, in 1, 5, 10ml respectively
  • All products have been extensively washed without centrifugation to remove trace elements from the supernatant (<0.000001% of trace elements)

Stability and Storage

The PELCO® NanoXact™ and BioPure™ gold colloids should be stored at 4°C.

  • DO NOT FREEZE.
  • NanoXact™ line is stable for >6 months after purchase

Product testing indicates increased stability can be attained by following the storage recommendations.

NEW PELCO® NanoXact™ Gold Nanospheres-PVP (dried)

Gold nanoparticle powder has two big advantages, it allows the user to determine the final concentration of the solution, and gives the user a choice in the type of solvent they wish to use (such as water, DMSO, ethanol, methanol, etc). The spheres are coated with PVP (polyvinylpyrrolidone), which helps maintain the stability of the particles when they are deposited.
