Nanotechnology

A high-quality nanomaterial is characterized by at least five different properties: particle size, particle size distribution, purity, stability, and reproducibility.

Small particle size: According to the EU definition, nanoparticles range in size from 1 to 100 nm. However, only particles smaller than 30 nm penetrate plant tissue, which is what makes them effective as fertilizers. For example, 99% of the silver nanoparticles from B+H Solutions are smaller than 20 nm.

Particle size distribution: The particles should not only be small, but also exhibit only slight differences in size.

Purity: The product must be free of heavy metals or organic contaminants; at B+H Solutions, the purity of the nanometal exceeds 99%.

Stability: While simple colloidal suspensions often lose their stability after just a few weeks or months, the nanomaterials from B+H Solutions remain stable for several years—they retain their shape and size.
