Learn about the science

MexBrain presents a patented combination of dialysis and nanotechnology for metal extraction. To that end ultrachelating compounds are associated to a biopolymer to extract the metals.

Extraction de métaux par des biopolymères ultrachélatants à travers une membrane de dialyse
After dialysis using MexBrain’s products, most of the toxic metals have been extracted

Using ultrachelating biopolymers present many advantages :

Low toxicity

Since there is no direct contact between the blood stream and our product, toxicity will be very limited. Through steps of synthesis and purification, we make sure that our product won’t be able to cross the dialysis membrane.

High efficiency / specificity

We used recognised chelates on our biopolymers, they allow for a high extraction efficacy while preserving a high specificity towards the targeted metals. Our specificity allows us not to have any impact on bio-essentials metals during the extraction


Our products are build in safe-by-design manner, using only chelates and biopolymers that have already been approved for clinical use. In addition to this, we provide a second level of safety by using low dialysis flow rates, thus limiting the risk of failure.


Our products can be adapted to any and all dialysis monitor, generators and devices. They already work with all dialyzers currently on the market and can target many different metals.
