Simble’s NanoSensor Detects Volatile Organic Compounds at Molecular Level

NanoSensor Demonstrates Molecular-Level Gas Detection

Simble Solutions Ltd (ASX:SIS) has taken a notable stride in sensor technology with its proprietary NanoSensor platform successfully detecting selected volatile organic compounds (VOCs) at low concentrations under laboratory conditions. This initial capability validates the design principles of its patented nanostructured sensor and establishes a baseline for further benchmarking.

The NanoSensor's ability to sense gases at the molecular level opens doors for applications in hazardous VOC detection, industrial safety, environmental monitoring, and workplace exposure assessment. The company has now moved into formal benchmark testing to rigorously evaluate sensitivity, selectivity, response time, and stability under conditions mimicking real-world use.

Nanostructured Design Targets Compact and Low-Power Sensing

Unlike conventional gas sensors that rely on surface interactions limited to a flat sensing area, Simble’s NanoSensor employs a proprietary high-surface-area nanostructured material within a sub-millimetre-scale platform. This three-dimensional architecture increases accessible interaction sites for target gases, aiming to achieve low-concentration detection without the need for larger, power-hungry devices.

This design approach could make the NanoSensor suitable for compact, portable, wearable, and field-deployable applications, addressing a known limitation of traditional sensors that often require scaling up size and power to improve sensitivity.

Commercial Relevance Across Multiple Safety and Environmental Markets

The NanoSensor’s initial detection profile includes gases such as acetone, ethylene, methane, hydrogen, carbon dioxide, and carbon monoxide. These VOCs are relevant to a range of monitoring contexts including industrial solvent exposure, food spoilage, emissions tracking, hydrogen safety, ventilation effectiveness, and combustion hazard detection.

Simble positions the NanoSensor as an extension to its existing commercial platforms, SimbleSense and CarbonView, which serve industrial and commercial customers in energy efficiency and sustainability reporting. The sensor’s data could feed directly into these platforms, enhancing ESG and Net Zero reporting capabilities alongside defence and safety applications.

Advancing Along a Structured Development Pathway

The gas detection workstream is the most advanced in Simble’s five-stage NanoSensor development pathway, which progresses from sensor fabrication through to customer trials. With fabrication and initial capability testing complete, the company is now engaged in formal benchmark testing to characterise performance under application-relevant conditions.

CEO Fadi Geha highlighted the significance of these results, noting the broad relevance of compact, low-power gas sensing to Simble’s existing customer base. He emphasised that formal benchmarking will provide detailed insights into the sensor’s sensitivity and stability, with further updates anticipated as the program advances.
