What is BIOZINY?

BIOZINY is a set of Advanced Materials based Antimicrobial Technologies for Surfaces and Spaces

BIOZINY Contains ZnO Nanoparticles as Active Ingredient. It is the world’s first ZnO nanoparticle-based antimicrobial coating.

Why Zinc Oxide?

ZnO is one of the safest materials with extraordinary properties!

Occupational Exposure Limits of Coatings are very important as the coatings are generally sprayed and the droplets remain suspended in the air for a long time. We see in the table above that the exposure limit of ZnO is the highest making it the safest and the same for Silver is the lowest making it the most unsafe.

Occu. Exposure Limits

Zinc Oxide is the safest of the Photocatalytic Materials having antimicrobial properties. The Occupational Exposure limits as set by different regulatory bodies are given below. Other materials used for their antimicrobial properties are Titanium Dioxide and Silver Nanoparticles or Silver Nitrate Nanoparticles.

As per tests conducted as per standard JIS Z 2801:2010 in a laboratory, BioZiny has the ability to kill 99.99% of E.Coli and 99.99 % of Staphylococcus Aureus within 24 hours of application*. The test has been conducted at The Bombay Textile Research Association (BTRA), Mumbai, India.

*Test Results are for a particular sample under laboratory conditions. We provide no guarantee on the replication of the same result in other conditions.

BioZiny Works Against Antimicrobial Resistance (AMR)

Antimicrobial Resistance is the ability of a microorganism (like Bacteria, Viruses, and some parasites) to stop an antimicrobial (such as antibiotic, antivirals and antimalarials) from working against it. As a result standard treatments become ineffective, infections persist and may spread to others. (Source: WHO)

Antibiotics have a downside: The more often these drugs are used, the more quickly bugs outsmart them.

Other than antibiotics, BioZiny is another way to deal with Bugs.

What is the active ingredient in BioZiny?
The active ingredient in BioZiny is surface modified Nano Zinc Oxide. Nano Zinc Oxide has demonstrated antibacterial properties against both Gram Positive and Gram Negative Bacteria. The antibacterial and antifungal properties of nano-zinc oxide have been thoroughly studied and the results are ubiquitous in scientific literature. The list of publications listed below extensively talks about the Antibacterial and Antimicrobial Properties of Nano ZnO.

Nano Zinc Oxide acts on bacteria on one or more of the following ways:

Very High Specific Surface Area:

Particles are less than 100nm in diameter thus having more pronounced antibacterial activities than large particles since the small size and high specific surface area allow better interaction with bacteria.


Release of Antimicrobial Ions:

Zinc Ions (Zn2+) exhibit antimicrobial activity. In aqueous suspension or when in contact with water, Zinc Oxide particles release Zinc Ions (Zn2+) that contributes to elimination of bacteria.


Direct Interaction of Nano ZnO particles with Bacteria:

The interaction between ZnO nanoparticles and bacterial cells is caused by electrostatic forces. The global charge of bacterial cells at biological pH values is negative, due to the excess of carboxylic groups, which are dissociated and provide a negative charge to the cell surface. On the other hand ZnO nanoparticles have a positive charge. As a result, opposite charges between the bacteria and Nanoparticles generate electrostatic forces, leading to a strong bind between the nanoparticles and the bacteria surface leading to disruption of the cell walls causing internalization of the nanoparticles in the bacterial cells. Nano ZnO causes great damage to the bacterial cells like disorganization of the cell walls, alteration of morphology and internal cell content leakage.



The surface of Nano ZnO has been considered to be abrasive due to presence of surface defects such as edges and corners. The bacterial cells are also damaged by the abrasive surfaces of ZnO Nanoparticles.


Generation of Reactive Oxygen Species (ROS):

Being a semiconductor with a band gap of approx. 3.3 eV, under the influence of radiation with photon energy more than its band gap, leads to the formation of an electron hole (h+). The electron hole (h+) reacts with H2O molecules (from the suspension of ZnO) separating them into •OH and H+. In addition, O2 molecules dissolved in the medium are transformed into superoxide anion radicals (O2 ̇−), which in turn react with H+ to generate (HO2 •). Subsequently, this species collides with electrons producing hydrogen peroxide anions (HO2−). Thus, the hydrogen peroxide anion reacts with hydrogen ions to produce H2O2 molecules, which is a very strong oxidizing agent. H2O2 molecules elevate the membrane lipid peroxidation that causes membrane leakage

of reducing sugars, DNA, Proteins and reduces cell viability.
