Nanometrology Capabilities

Determining the physical and chemical properties of nanomaterials poses significant challenges, especially in conditions relevant for practical applications. A comprehensive understanding of these materials requires infrastructure and expertise that cover multiple measurement techniques.

Capabilities and Expertise

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, our facilities provide a range of nanometrology services that are unique in Australia.

Our expertise and capabilities are underpinned by:

  • development of a metrological scanning probe microscope as Australia's primary nanoscale length standard
  • investigation, comparison and development of nanoscale measurement instrumentation and methodology
  • development of methods to characterise sizes and size distributions of nanoparticles in relevant matrices such as sunscreens, wastewater and cell culture media
  • on-going research and development in nanometrology

We welcome collaborative partnerships, both within Australia and internationally, and provide internships for Australian and international students.

Nanometrology Services

Our nanometrology services, shown in the table below, include:

  • nanoscale dimensional measurements that are traceable to the SI definition of the metre
  • physical characterisation as well as chemical analysis of nanomaterial
  • method development to suit customer requirements
  • access to measurement facilities for clients, collaborators and students
  • consultancy and training on nanoscale measuring techniques and relevant terminology

Our characterisation facilities are supplemented by sample and materials processing equipment, including a high-intensity ultrasonic processing system, sample dividers/rifflers and centrifuges.
