Our high-scale production units do allow the production of single batches till 100L- scale.
Our gold particles are synthesized using citrate reducing and stabilizing agent. Citrate salts weakly interact with nanogold by electrostatic interactions and therefore can be easily displaced by adding any biomolecules like antibodies, receptors, DNA, aptamers and any other proteins. Proteins, thanks to their chemical composition, create very strong and stable interactions with gold by combining different types of interactions like electrostatic, hydrophobic and coordinate covalent bounds. Optimizing the pH of your gold colloidal solution will ensure proper conjugation of any biomolecules.
Using Nano Flow Gold allows rapid test developers to reach high sensitivity and precision taking advantage of the high sphericity of our gold particles. When two spheres are in interaction, they generate a weak interaction energy due to their single contact point. On the opposite of particles containing sharp edges, the association of two spherical particles is reversible minimizing the appearance of aggregates. This maximizes the gold surface area to attach antibodies and reach outstanding sensitivities. The high monodispersity and the absence of any odd shapes in Nano Flow Gold make our gold colloids precursors of highly precision rapid diagnostic tests.
