These are solid spherical silica nanoparticles without functionalization. Available in powder form quantities of 1g, 10g, 50g and 100g. Available as a mono-dispersion in quantities of 25ml, 100ml and 500ml at 10wt% (100g/L) SiO2 in either H2O or Ethanol. Certificate of Analysis includes SEM images.
GE&R silica nanoparticles are synthesized using a Stober method to provide very high purity (+99.999%) spherical particles with narrow size distribution. Bulk pricing is also available.
Custom sizes and quantities are also available.
