We engineered a next-generation molecular nanocoating, Invisi Smart Shield™, that uses photocatalytically-activated titanium dioxide (TiO2) impregnated with silver zeolite. Titanium dioxide is a nontoxic FDA and EPA listed molecule that is used to eliminate and remove virulent particles.
Our titanium dioxide-based formula has demonstrated powerful and consistent efficacy through the generation of reactive oxygen species (ROS) under photocatalysis.
Invisi Smart Shield™ has been proven to destroy organic and inorganic substances that come into contact with it. Viruses, bacteria, fungi, volatile organic compounds (VOCs) and pollutants are quickly decomposed and converted into water (H2O) and carbon dioxide (CO2).
This powerful combination of disinfecting agents has been restricted in both clinical and industrial settings due to a lack of application possibilities. Invisi Smart Technologies has successfully overcome this obstacle and is now able to offer this groundbreaking formula outside of the lab.
By manipulating the molecular compound of our formulation of titanium dioxide and silver zeolite, we have bottled its sanitising powers and made them commercially available with a simple application process.
The Invisi Smart Shield™ coats any surface with a layer of disinfecting particles that continuously protects for up to 5 years from application.
Decomposes viruses and bacteria
The mode of action of our photocatalytic antimicrobial coating can be described by the generation of potent oxidising radicals on a semiconductor surface after light absorption, in the presence of oxygen and water. The spectrum of natural and most artificial light sources, overlap suitably with the band gap of the semiconductor to produce radicals.
In other words, reactive oxygen species (ROS) are created by the irradiation of the semiconductor, titanium dioxide.
These in turn, exert potent microbicidal activity upon contact with various microbes, which is regenerated through further exposure to light — a highly desirable property of self-renewal.
The immune system uses ROS to eradicate any unknown invader as a first defence. Invisi Smart Shield™ uses this natural response to kill pathogens.
Titanium dioxide, a naturally occurring mineral, is considered stable, slow degrading and the development of resistance is not expected.
We have developed the tools for a new coating process. Our dedication to finding shielding innovations has culminated in a product with higher performance levels than available disinfectants. We are able to provide increased surface coverage and greater durability in our coating solution within a thin transparent film.
We are committed to honing our toolbox in preparation for the future — providing unique solutions to an ongoing, global problem.
Simple and fast process
Controlled film thickness (1-2μm transparent film)
Coating large surface areas in a short time period
Tight surface binding and long-lasting action
The Invisi Smart Shield™ is seamlessly applied to virtually any surface using a spray gun apparatus.
The area to be treated is initially prepared by thoroughly cleaning its surfaces.
Using a specialised apparatus, a technician applies 5-year Invisi Smart Shield™ primer and topcoat.
After primer and topcoat application, drying is required for 15 minutes. The surface is actively protected.
The durability of our 5-year technology relies on our unique applicator gun. A long-lasting effect is achieved with the combination of our Invisi Smart Shield™ coating solution and our bespoke precision spray gun.
The area to be treated is initially prepared by thoroughly cleaning its surfaces.
Using a spray gun, a technician applies 1-year Invisi Smart Shield™. Drying is required for 15 minutes.
For optimal efficacy we recommend use of the patented Twin Air pressure and gravity spray guns* (Twin Air Spray Systems Ltd), which can operate at over 95% Transfer Efficiency (TE)

According to the WHO, effects of ambient (outdoor) and household air pollution cause 7 million premature deaths per year, globally.
3.8 million of these deaths are attributed to indoor pollution and make up 7.7% of global mortality. Exposure to indoor air pollutants can lead to a wide range of adverse health outcomes in both children and adults, from sick building syndrome (SBS) to respiratory illnesses and cancer.
Mould spores and gaseous outputs from building materials, furniture, appliances and personal care products can significantly affect wellness and health.
Exposure and inhalation of a variety of health-damaging pollutants, including particulate matter (PM), methane, carbon monoxide, polyaromatic hydrocarbons (PAH) and volatile organic compounds (VOC) result in increased mortality from cerebral and myocardial infarctions, cardiovascular diseases (CVDs), to chronic obstructive pulmonary disease and lung cancer.
Invisi Smart Shield™ can help prevent this prevalent and recurring burden for society and healthcare systems.
Invisi Smart Shield™ is able to decompose organic and pathogenic substances in the air when they come in contact with treated walls and ceilings, which are then converted into completely harmless substances. Additionally, titanium dioxide inhibits static electricity allowing particles to ground and suppresses indoor dust.

Waterborne diseases caused by pathogenic microorganisms have gained increasing importance as they have a direct affect on human health.
Photocatalysed titanium dioxide has been extensively researched due to its environmentally encouraging properties and its application to water-contact surfaces.
Studies have demonstrated that titanium dioxide improves the efficiency of disinfection by the effective inactivation of pathogenic microorganisms such as bacteria and algal toxins.
In the US, pathogen-specific illness and cost estimates associated with 13 diseases that can be transmitted by water are staggering. According to the Centres for Disease Control and Prevention (CDC), deaths, emergency department (ED) visits, and hospitalisations are caused by:
Invisi Smart Shield™ delivers continuous antimicrobial efficacy on surfaces that are constantly exposed to water. Titanium dioxide is widely acknowledged as an eco-friendly solution that reduces harmful by-products that can form, especially in medical and food processing industries.
