Nanoparticles serve as significant research tools in better understanding and unravelling the mysteries embodied in nanotechnology research. Colloidal gold particles, in particular, are both excellent catalysts for nanowire growth of a variety of materials and active sites for SERS (surface enhanced Raman scattering). The colloidal gold particles are applied with a proprietary process and baked in air at 250°C to create high purity gold particles secured on the substrate. The line of the Gold Nanoarrays are unique products that provide:
- Substrate particle densities suited to SERS or material growth
- A choice of available substrates
- Excellent batch size uniformity and uniform particle distribution
- Highly stable products
Uniform and regular coverage of nanoparticles is highly desirable for systematic and reproducible results. Ordered arrays are ideal. Gold Nanoarrays overcome the problems associated with other methods:
- The high cost of electron beam lithography
- The random dispersion from adsorption or evaporative colloid deposition
The Gold Nanoarrays are available on a number of substrates:
- Glass: 5 x 10mm
- Quartz: 5 x 10mm
- Silicon: 5 x 10mm The gold nanoparticles have the following characteristics:
- 15 or 30nm average particle diameter
- Excellent uniformity and particle distribution
- Normal density coating for material growth
- High density coating for SERS
