What are green synthesized gold nanoparticles?
The green gold nanoparticles are produced by green chemistry (by bio-reduction of metal salts HAuCl4), with crude and / or purified extracts from plants. These extracts have the double action of reducing the metal and stabilizing the nanoparticle formed. The size and shape of the gold nanoparticles formed can be modulated by various factors during the synthesis. The synthesis of nanoparticles by using the bio-reducing potential of plant extracts has been demonstrated in various studies in recent years. Based on this observation, TORSKAL developed a green chemistry approach to synthesize nanoparticles using endemic plants originated from Reunion Island. Plants extracts have the double action of reducing the metal and stabilizing the formed nanoparticles.
The obtained colloidal gold or gold colloidal suspension are fully characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), zeta-potential, XRD, UV-Vis, FTIR and Raman spectroscopy to understand their physicochemical and biological properties.

TORSKAL’s green gold nanoparticles, lyophilised plant extract, plant powder and dried plant leaves
The unique properties of TORSKAL’s green gold nanoparticles:
Conformity
We employ an environmentally friendly technique for the production of well-characterized gold nanoparticles.
Salt resistance
Stable over 0.4 M NaCl, which is 5 times higher than gold nanoparticles synthesized by the citrate reducing method.
Scalability
Our process of producing gold nanoparticles or colloidal gold is very straightforward to scale up with a lower risk of contamination.
Biocompatibility
Our green synthesis process does not require toxic chemicals, which makes our products suitable for biomedical applications.
High purity
Our gold nanoparticles are of high purity with the absence of aggregation, which makes them monodisperse gold nanoparticles.
High stability – For at least 3 months
Our gold nanoparticles are more stable than Turkevich gold nanoparticles in a saline environment, over time, and after centrifugation.
