How It Works:
The Science Behind Zetrisil®

The Germfree Innovations product line is formulated with Zetrisil®, an antimicrobial shield that provides long-term protection. Zetrisil covalently bonds to surfaces, forming a matrix of microscopic “swords” with a high positive charge, known as high “Zeta Potential.” This high Zeta Potential means that negatively charged microbes will be drawn to the shield, where the matrix of swords will do its work. Alternatively, most conventional disinfectants have low Zeta Potential. Read on for more details.

Zeta Potential

What is Zeta Potential?

Zeta Potential is the analysis technique for determining the surface charge of nanoparticles in solution (colloids). Nanoparticles have a surface charge measured in millivolts, that attracts a thin layer of ions of opposite charge to the nanoparticle surface.

Why is Zeta Potential Important for Disinfectants and Sanitizer?

The greater the positive charge disinfectants or sanitizing solutions has the greater killing effect against negatively charged bacteria and virus, by way of opposite pole magnetic attraction.

How Does Zeta Potential Improve the Efficacy of Disinfectants and Sanitizers?

The majority of bacteria and virus are negatively charged nano particles, with a positively charged disinfectant & or sanitizer they will be attracted to each other and agglomerate the negatively charged bacteria or virus particles around the positively charged disinfectant or sanitizer solution therefore improving the kill time and efficacy rate per volume of liquid or disinfectant or sanitizer.

Can Zeta Potential Kill Bacteria and Viruses Magnetically?

Yes, by way of changing the magnetic charge around bacteria or virus cell, which can damage the cell wall membrane, causing osmosis imbalance to the bacteria or viruses. This causes their cell wall to rupture, lyse and explode.

Zeta Potential Assessment

An aliquot of 10 mL was taken from each sample and placed in the zeta check cylinder. Each measurement was completed in 30 seconds. Analysis was performed in duplicate. Results are summarized in Table 1. It was found that both the samples showed incipient stability.
