Invisi Smart Shield

Invisi Smart Shield™ Technology

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.

The Formulation

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).

Why Invisi Smart Shield™

Spraying away infection

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.

Tightly binding to the surface, the Invisi Smart Shield™ respects the aesthetic, form and function of the object it is applied to. The Invisi Smart Shield™ is gentle and safe for humans and the environment.

An Innovative Solution

Common disinfectants do not eradicate all microorganisms, they leave inert residual matter on the surfaces they have been used on and immediately allow biofilm build-up.

Standard disinfection

Does not kill all pathogens and leaves residual matter of inert viruses and bacteria

Sterilisation

Kills all pathogens and leaves residual matter of inert viruses and bacteria

Photocatalytic disinfection

Decomposes viruses and bacteria

The photocatalytic reaction of titanium dioxide has been proven to destroy a wide range of organisms converting them into carbon dioxide and water.

Activated by Light

Our Invisi Smart Shield™ provides an invisible protective layer of 1-2μm that is effective even with a light sources below 540nm.

Photocatalytic Reaction

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.

Invisi Smart Shield™ fights against the build-up of bioburden on treated surfaces. Biosafety and reduction of infectivity are at the core of our testing standards.

  • Invisi Smart Shield™ was tested on surfaces against viral, bacterial and fungal strains following exposure to ultraviolet and incandescent light and was performed in accordance with BS ISO 27447; ISO 18184; JIS Z 2911: 2009, respectively. Testing was conducted both in the presence and in the absence of light.
  • Testing on 3-ply face masks with Invisi Smart Shield™ has been proven effective against Middle East Respiratory Syndrome coronavirus (EMC/2012).
  • Influenza A was also chosen for testing due to its effective infectivity rate as well as its resilience in volatile environmental conditions (especially to the presence of pH, temperature and humidity).
  • SARS-CoV-2 viral testing is being conducted at the University of Cambridge and the Danish Technological Institute (results pending).

Air Pollutants

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.

Factors that contribute to indoor air pollution include:

Poor air conditioning

Mould spores and dust mites

Building materials and furniture

Electrical equipment

Emissions from cooking or heating

Personal hygiene products

Air Purification

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.

Our Solution

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.

Coating air filters and air filtration systems provides an additional layer of security for air purification strategies.

Uses

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:

  • Acute otitis externa
  • Campylobacteriosis
  • Cryptosporidiosis
  • Escherichia coli (E. coli) infection
  • Free-living ameba infection
  • Giardiasis
  • Hepatitis A virus (HAV) infection
  • Legionnaires’ disease
  • Nontuberculous mycobacterial infection
  • Pseudomonas-related pneumonia
  • Salmonellosis
  • Shigellosis
  • Vibriosis or cholera

6,939 total annual deaths were documented and 477,000 annual ED visits were made with a treat-and-release ED visit cost of USD 3.8 billion.

Shielding you from contamination

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.
