Business focus and technology
Micromem describes its core activity as the development and commercialization of sensor platforms that can provide real-time intelligence in detection systems. The company highlights expertise with sophisticated sensor applications and nanowire sensor technology. In its public updates, Micromem notes work on nanowire-based gas sensors and liquid-phase biochemical sensors, as well as collaborations aimed at advancing nanowire sensor technology from research toward commercial applications.
The company reports that it has access to proprietary innovations in nanowire field-effect transistor sensor technology through a collaboration with the University of Toronto and the Canadian Department of National Defence. This work focuses on detection sensitivity at very small charge levels and includes applications in biochemical agent detection and other sensing markets. Micromem indicates that these developments support potential use in defense-related sensing, environmental monitoring, and biomedical diagnostics.
Industry applications
In its public descriptions, Micromem states that it targets multiple industries where detection accuracy and real-time data are important. The company cites applications and opportunities across:
- Oil & gas
- Utilities
- Automotive
- Healthcare
- Government
- Information technology
- Manufacturing
- Other industrial and environmental markets
Micromem notes that its platforms are intended to serve industries that require accuracy, durability, and real-time intelligence in detection systems. The company also reports that some of its sensor technology originated from defense-related projects and is being advanced toward broader commercial use.
Selected technology developments disclosed by the company
In its news releases, Micromem has described several specific sensor technology developments:
- A nanowire-based gas sensor platform designed for high-sensitivity gas detection. The company reports that this platform uses a multi-nanowire sensing array and includes an electrical bias control feature that allows tunable amplification for enhanced detection performance across various gas types and concentration ranges. Micromem states that the platform is fabricated using standard photolithography processes and is intended to be cost-effective and scalable for high-volume industrial applications.
- A liquid-phase nanowire biochemical sensor platform engineered to detect disease-associated biomarkers at ultra-low concentrations. According to Micromem, this sensor is designed for early medical diagnostics and is also fabricated using standard photolithography processes to support scalability for industrial production. The company notes that the initial target analyte is TREM-1, a biomarker associated with inflammatory responses and a range of diseases.
- Work under a project titled “Development of a Nanowire Field Effect Transistor Biochemical Sensor,” led by a University of Toronto research team, with Micromem as a partner. The company states that this project is aimed at developing miniaturized, low-cost, efficient, and selective sensors based on InAs nanowires that can be deployed on both aqueous and gas-based platforms for a wide variety of analytes.
Micromem’s disclosures indicate that these sensor platforms are intended to be adaptable to different analytes and gases, with potential use in defense, environmental monitoring, industrial safety, and biomedical applications. The company also notes that some of the technology has demonstrated detection capabilities down to very low concentration levels in research settings.
Collaborations and research relationships
Micromem has publicly discussed a collaboration with the University of Toronto and the Department of National Defence in Canada. Under a research collaboration agreement, the parties are working on nanowire field-effect transistor biochemical sensors. Micromem notes that the project builds on work that began several years earlier and that it has achieved promising developments in technology for military and industrial applications in state-of-the-art biochemical sensors.
The company has also reported that the University of Toronto team involved in the collaboration has published research on nanowire sensor technology in scientific journals. Micromem describes this body of research as demonstrating the potential of one-dimensional nanowire structures in sensing applications and as a foundation for the company’s efforts to commercialize high-performance sensors.
