Nanotechnology Research Programs/Activities:

The National Measurement Institute (NMI) develops, maintains and delivers the measurement infrastructure, expertise, standards and services Australia requires. As part of those activities, NMI’s Nanometrology Section provides measurement standards and services for nanotechnology to assist Australian researchers and industries to capitalise on growth and commercialisation opportunities, and contribute to effective health, safety and environmental regulation for nanotechnologies.

The development and use of nanotechnologies by Australian industry is increasing, and more and more nano-enabled products are entering the market. Accurate length measurements at the nanoscale are critical for underpinning the development, use, and regulation of these products. The nanometrology standards and services provided by NMI link accurate nanoscale measurements traceable to the SI meter to real-world applications in research, manufacturing, trade and regulation so that Australian researchers, industry, regulators and consumers can have confidence when making decisions on nanotechnology.

We have established state-of-the-art facilities with a wide range of instrumentation for the characterisation of nanomaterials. Coupled with our staff’s expertise, these facilities provide a range of nanometrology services that are unique in Australia.

Our research activities are aimed at the development of new standards, measurement techniques and calibration services for nanostructures and nanomaterials. This includes the investigation and comparison of accuracies, limitations and measurement uncertainties of nanoscale measuring instruments and methods. Some of our current research and development activities include:
• Development of a metrological atomic force microscope as Australia's reference standard for nanoscale dimensional measurements, traceable to NMI's internationally recognised primary length standards;
• optimisation of data processing and analysis to improve resolving power and accuracy of dynamic light scattering measurements for polydisperse nanoparticle suspensions;
• development of methods to characterise sizes and size distributions of nanoparticles in application-relevant matrices such as sunscreens and wastewater;

NMI actively participates in the development of documentary standards for nanotechnologies at both the national and international level. Group members contribute to the work of Standards Australia’s Technical Committee NT-001 (Nanotechnologies) and are represented in the Australian delegation to the International Organization for Standardization’s Technical Committee TC 229 (Nanotechnologies). We also support pre-normative research through membership in the Steering Committee of the Versailles Project on Advanced Materials and Standards (VAMAS). This work helps to ensure that developments in Australia and overseas remained aligned, to the benefit of researchers, industry and regulatory bodies, and through them all Australians.

NMI’s nanometrology team works in close collaboration with other NMI colleagues, and with external collaborators and clients, to deliver fit-for-purpose, multi-faceted and multi-disciplinary measurement solutions. We are happy to discuss specific nano-measurement needs and issues and welcome suggestions for research collaborations and enquiries for student placements.
