Advancing Scientific Discovery with Multimodal Microscopy in Australia
Scientific progress relies heavily on the ability to observe the invisible. Recognizing this fundamental need, The University Of Western Australia has significantly expanded its analytical capabilities by installing a state-of-the-art multimodal microscopy suite. This $20 million investment, supported by university funding alongside State and Federal Government contributions through NCRIS Microscopy Australia and ARC LEIF, provides researchers with the precise imaging tools required to solve complex national challenges.
Located within UWA’s Centre for Microscopy Characterisation and Analysis—the Western Australian node of Microscopy Australia—this new infrastructure enables scientists to conduct highly advanced, correlative imaging. Rather than relying on a single visualization technique, researchers can now combine multiple imaging modalities to examine samples from the macro scale down to the nano scale. This comprehensive approach eliminates analytical blind spots, providing a complete picture of complex biological, chemical, and physical structures.

Key Imaging Tools Installed at UWA’s Centre for Microscopy Characterisation and Analysis
The newly launched suite is not merely an incremental upgrade; it introduces entirely new capabilities to the region. By bringing together distinct imaging technologies under one roof, UWA has created a centralized hub for high-resolution analysis that serves both academic institutions and commercial enterprises across Australia.
Understanding the Nano-SIMS Capability
The centerpiece of this expansion is the acquisition of a high-resolution nano-Secondary Ion Mass Spectrometry (nano-SIMS) instrument. This piece of equipment is exceptionally rare—it is one of only three currently operational in the world, and it is the only high-resolution nano-SIMS in Australia. The nano-SIMS allows researchers to capture elemental and isotopic images at a resolution a few thousand times smaller than the width of a human hair, making it small enough to see inside an individual cell.
In practical terms, this means scientists can map the exact distribution of specific molecules, isotopes, or elements within a sample without destroying its overall spatial context. For example, if a pharmaceutical company is developing a new type of targeted drug, the nano-SIMS can track exactly where the drug travels within a cellular structure and how it interacts with specific organelles. This level of precision drastically reduces the time required to understand drug efficacy and cellular toxicity.
Light Sheet Microscopy and SBF-SEM
Complementing the nano-SIMS is Western Australia’s first light sheet microscope, funded through ARC LEIF. Light sheet fluorescence microscopy is uniquely suited for imaging large, living samples over extended periods. Unlike traditional confocal microscopes that scan a sample point by point—often causing photobleaching and phototoxicity—light sheet microscopy illuminates a single, thin plane of the sample while the camera captures the entire plane at once. This gentle approach is critical for developmental biology, allowing researchers to observe embryonic development or neural activity in real time without harming the specimen.
Additionally, the suite includes a state-of-the-art Serial Block Face – Scanning Electron Microscope (SBF-SEM). This imaging tool is designed for high-throughput 3D reconstruction. It works by repeatedly scanning the surface of a resin-embedded sample with an electron beam and then using an ultra-microtome inside the chamber to shave off a thin layer of the block face. This process repeats hundreds or thousands of times, generating a stack of high-resolution images that can be compiled into a detailed three-dimensional model. SBF-SEM is particularly valuable for mapping the intricate connectivity of brain tissue or analyzing the pore networks within geological samples relevant to critical minerals extraction.
High-Resolution Confocal and LG-SIMS Upgrades
Rounding out the suite are a new high-resolution confocal microscope and a significant upgrade to the existing Large Geometry Secondary Ion Mass Spectrometry (LG-SIMS) funded through Microscopy Australia. The high-resolution confocal microscope provides exceptional optical sectioning capabilities, allowing researchers to capture sharp, high-contrast images of thick biological specimens. The LG-SIMS upgrade, on the other hand, enhances the facility’s ability to conduct high-precision isotopic dating and geochemical mapping over larger sample areas, which is vital for geological and environmental research.

Aligning Imaging Tools with National Research Priorities
Australia faces specific, pressing challenges in sectors ranging from energy production to medical science. The strategic deployment of these advanced imaging tools is directly aligned with addressing these national research priorities, ensuring that the scientific community has the practical resources needed to deliver tangible outcomes.
Energy and Critical Minerals Exploration
As the global demand for clean energy technologies surges, securing a reliable supply of critical minerals has become a paramount concern for Australia. Understanding the genesis of ore deposits and the distribution of valuable elements within rocks requires analysis at the micro- and nano-scale. Using the SBF-SEM and the upgraded LG-SIMS, geologists can reconstruct the 3D architecture of mineral veins and identify the specific chemical environments where rare earth elements concentrate. This data directly informs more efficient and environmentally sustainable extraction and processing techniques, reducing the energy footprint of mining operations.
Agriculture and Environmental Monitoring
In the agricultural sector, understanding how plants interact with their soil microbiome at the cellular level is crucial for developing crops that are more resilient to climate change and drought. The combination of light sheet microscopy and confocal imaging allows plant biologists to visualize root growth and nutrient uptake in living plants over time. Furthermore, the nano-SIMS can be used to trace the uptake of specific fertilizers or soil contaminants, measuring exactly how much of a nutrient makes it into the plant tissue versus washing away into the environment. This precision helps optimize fertilizer use, protecting local waterways from agricultural runoff while maximizing crop yields.
Health and Medical Research
Medical research requires an intimate understanding of cellular mechanics to develop effective treatments. As noted by UWA Deputy Vice-Chancellor (Research) Professor Anna Nowak, the nano-SIMS provides an unprecedented window into cellular function. By tracking isotopically labeled compounds, medical researchers can observe metabolic pathways in action, study how pathogens invade host cells, and evaluate the intracellular delivery of novel therapeutics. This capability accelerates the preclinical testing phase for new drugs, bringing potential treatments for diseases like cancer and neurodegenerative disorders closer to clinical trials.
