Our carbon nanomaterial products are prepared by exfoliation of graphite in a planetary mill using two types of exfoliating agents, in the absence of solvents and mineral acids. Our work-up procedure guarantees the removal of any remaining exfoliating agent.

Few Layer Graphene 150-500nm
The preparation of the other 2D nanomaterials proceeds in similar procedure as before. These are prepared by exfoliation of its original bulk material in a planetary mill using biocompatible exfoliating agents, in the absence of solvents and mineral acids. As before, our work-up procedure guarantees the removal of any remaining exfoliating agent.

Molybdenum disulfide (MoS2) 300-400nm
Wolfram disulfide (WS2) 300-400nm
Nanoparticles Anchored on 2D Nanomaterials
We have developed a new methodology where it is possible to obtain exfoliated nanomaterials including graphene and TMDC (WS2 and MoS2), decorated with different nanoparticles, such as copper, niquel, titanium oxides and metalic silver and cobalt.

All products are supplied in powder form and can be easily dispersed in water (and other media) as shown in the published video (here).
All batches of our products are characterised by Raman spectroscopy, HRTEM (High Resolution Transmission Electron Microscopy), TGA (Thermogravimetric Analysis), TXRF (Total X-ray fluorescence), Elemental Analysis, and Sheet Resistance. Each sample supplied will be accompanied by the characterisation data and spectra.
The dispersions in aqueous media are stable during the first 24 hours. After that time some of the graphene may precipitate but, if this occurs, it can be redispersed by brief ultrasonication (cycles of 10 seconds, no more than 2 minutes). This methodology ensures a good dispersion of the graphene.
Our carbon nanomaterial products have been widely used for a variety of applications such as:
Our carbon nonmaterial products can also be dispersed directly in culture medium (recommended concentration of around 0.1 mg/mL) and such samples would be stable during several hours. Stabilising agents are not required.
Recommendations for storage:
Our products are stable at room temperature and refrigeration is not required during storage.
