March 2026 | 11 For decades, disinfection has been almost exclusively performed through the traditional two-dimensional method of scrubbing and wiping. While this method has been widely considered “good enough”, even the most rigorous two-dimensional disinfection methodologies have systemic deficiencies in effectiveness and is subject to human error. In comparison, three-dimensional disinfection extends beyond the surface to include the air above, disinfecting rooms whilst also providing preventative protection. Even with the introduction of three-dimensional disinfection, efficiently distributing active substances in controlled environments has long been a technical challenge. Conventional fogging systems are often impacted by a fundamental limitation: very fine particle sizes are typically achieved only at low output rates, while highcapacity systems tend to produce larger droplets that quickly settle on surfaces. These challenges have been directly addressed through Biotech3D’s unique technological approach. Biotech3D’s technology represents a scalable aerosol delivery platform that is capable of efficiently distributing active substances in enclosed environments with particle sizes below 5µm at industrially relevant output rates. This allows the system to combine two characteristics that are rarely achieved simultaneously within the disinfection space: fine aerosol particles and high output performance. The Biotech3D D2400 system is designed to generate several kilograms of aerosols per hours, whilst maintaining its groundbreaking fine particle size distribution capabilities. In practical operation, the system regularly achieves more than 3 kg/h aerosol output, with maximum performance levels of up to approximately 4 kg/h, depending on operating conditions. Despite this high throughput, the system produces a stable aerosol cloud that is capable of distributing evenly within enclosed spaces. This allows the rapid treatment of indoor environments, as well as complex geometrics such as cavities, ventilation systems, and technical installations. In doing so, Biotech3D D2400 eliminates unwanted germs, such as resistant MRSA bacteria, E.coli, dangerous noroviruses and flu viruses, in addition to counteracting various fungi, yeasts, and organic odours. A key component of this innovative platform lies in its interaction between aerosol generation and airflow management. Inside the device, airflow is guided in a way that allows aerosol particles to be efficiently entrained and stabilised while larger droplets are retained within the system. This multi-stage airflow architecture helps to generate a stable aerosol cloud and minimises unwanted wet deposition on surfaces. As a result, the system can efficiently distribute active substances in even the most complex environments. In addition to aerosol technology, the Biotech3D concept also incorporates polymer-based active substances in certain applications. In doing so, it boosts the potential residual or depot effect of the active disinfecting substances, meaning that Bacteria and viruses maintain their infectivity on surfaces for extended periods, often remaining silently present in our environment for weeks, or even months. Thousands of individuals fall ill each year as a result, with significant damage caused to the public health and economy over time. These adverse effects can be significantly mitigated through the consistent use of 3D disinfection, an ethos championed wholeheartedly by Australian technology developer Biotech3D. We explored Biotech3D below, as it is named in the Technology Innovator Awards 2025. Best 3D Ultrasonic Disinfection Technology 2025 antimicrobial components are more likely to remain on the treated surfaces and help reduce microbial colonisation over extended periods. Microbiological investigations conducted in accordance with international test standards – such as ISO 22196 – have demonstrated significant reductions in bacterial contamination, including microorganisms such as MRSA. By combining efficient aerosol distribution with polymer-based antimicrobial technology, Biotech3D has opened up a whole host of possibilities for hygiene-related applications. The technology has already been applied in a variety of practical scenarios, including building sanitation and mould remediation; odour neutralisation in vehicles and interior environments; the treatment of technical installations and cavities; and hygiene-related applications within enclosed spaces. The world’s growing focus placed on hygiene, indoor air quality, and environmental treatment means that technologies with the capability to distribute active substances in enclosed spaces are becoming more important than ever. Biotech3D intends to remain at the forefront of this growing industry by further developing its aerosol platform, with additional patents that focus on advanced airflow architectures and aerosol conditioning technologies. In anticipation of such developments, Founder Harald Rauchenschwandtner told us: “The goal is to provide scalable solutions for environmental treatment, hygiene applications, and building technology in a wide range of industries.” Since its inception, Biotech3D has been instrumental in shaping the advancement of three-dimensional disinfecting and introducing new possibilities for the controlled distribution of active substances in controlled environments. For its significant contributions to myriad sectors, driven by an unrivalled combination of advanced aerosol engineering and polymer-based antimicrobial strategies, Biotech3D has been recognised as the Best 3D Ultrasonic Disinfection Technology 2025.
