Indoor Air Quality

Indoor air quality (IAQ) maintenance has been a perennial topic in our urban society. With the COVID-19 pandemic compounding the need to improve the quality of air in our living and working spaces, there are opportunities for technological innovations to overcome this multi-faceted challenge. The Indoor Air Quality Tech Bundle features a curated list of technologies that enterprises can license or co-innovate with technology providers to create new products and services for the growing IAQ market. Enterprises can explore a range of solutions for reducing indoor air pollution, enhancing ventilation and air cleaning, controlling indoor temperature and humidity, as well as monitoring and testing, to address various needs along the IAQ value chain.

Fast Dissolving Concentrate Tablet for Cost Efficient Hand and Surface Sanitisers
Extensive sanitation needs arising from COVID-19 are adding high costs to both businesses and consumers. Such costs are mostly related to the supply chain, and involve processing, transportation, and storage of dangerous substances. Furthermore, the packaging of finished sanitation products consumes large amounts of shelf space at the point of sale − not to mention the negative environmental impact of the packaging materials. To address these issues, fast dissolving concentrate tablets are developed based on a proprietary encapsulation technology. These fast-dissolving concentrated tablets can quickly transform water into an alcohol-free hand or surface sanitiser.
Stable, Plant-based Photoactive Antimicrobial Agent
Antimicrobial resistance developed due to the overuse of conventional antimicrobial agents in surface coatings and consumer products is a global concern for treatment of infectious diseases in recent years. To address this concern, US FDA has banned the use of a number of conventional antimicrobial agents in consumer and healthcare products such as hand soaps and hand sanitisers. This raises the importance of alternative antimicrobial agents in antiseptic products. Photoactive antimicrobial agents are effective alternatives which produce highly reactive oxygen species (ROS) when activated by light. These reactive oxygen species display broad-spectrum biocidal activity that destroy microbes by a multi-targeted killing mechanism, which may limit the development of antimicrobial tolerance or resistance. The researchers have developed a stabilised form of a plant-based antimicrobial agent to protect it from environmental degradation. The enhanced environmental stability of this natural photoactive antimicrobial agent has made it suitable to be incorporated in various materials for the self-sterilising product applications and may provide a “greener solution” to limit the spread of pathogens and transmission of infections by indirect contact.
Customizable Sensor Platform for Highly Specific Analyte Detection
This is essentially a highly specific molecular sensor based on cutting edge optical sensing technology. It is completely label-free, with ultrahigh sensitivity in the nanomolar to picomolar range. In addition, the detection response can be observed in real-time and the technology can be customized to detect different analytes in various applications. This technology allows for versatility in the type of analyte to be detected, which can include analytes not detected by existing techniques or those not detected by these techniques at the required sensitivity and specificity. 
Coating with Odourless Microorganisms to Improve Indoor Air Quality
Air-conditioning systems are indispensable for human daily life. Clean air is recognised as an integral component in human health and well-being while offensively smelling or polluted air severely spoils a pleasant environment. However, microbial activity and offensive odours in indoor air continue to be an issue in indoor environments such as in automobiles or airplanes. Although various types of fragrances are commercially available for removing offensive odours, they do not fundamentally remove the moulds and bacteria proliferating on the evaporator core but merely dilute the unpleasant odour temporarily. Also, the antibacterial agents that are commercially available at present are not developed to specifically act on particular moulds or bacteria proliferating on the evaporator core. To address this, an eco-friendly air purification technology was developed using a biofilm coating containing odourless microorganisms to improve indoor air quality, in particular, in air-conditioning systems such as in automobiles.
Polymeric Resin Additive Paste to Achieve Photocatalytic Effect in Indoor Environments
Photocatalytic effect is a crucial element for achieving self-cleaning surfaces in an indoor environment. Self-cleaning surfaces minimise the need for labour intensive and costly cleaning and maintenance services. However, commercially available self-cleaning solutions are typically in the form of coatings that wear off with time and require re-application, which is costly and time consuming. In view of the limitations of such self-cleaning coatings, a polymeric resin additive paste that enables long term photocatalytic effect using visible light has been developed.
