Uncompromising Safety

We Can. But We Won't.
The crystallized porous β-cyclodextrin standard.

While others use MOF(Metal-Organic Frameworks), BYNANO insists on COF(Covalent Organic Frameworks).

Why? To eliminate even the 0.01% risk of metal toxicity.
The crystallized porous β-cyclodextrin(β-Cyclodextrin COF) is pure organic. 

Safe for skin & planet. That's our promise. 

We build with Carbon, Hydrogen, and Oxygen only. 

This is not just technology; it is our promise of safety.
