PhD Student’s work highlighted in Advanced Healthcare Materials
Daniela Duc has had her work, which was performed in part at the ANFF-Vic Biointerface Engineering Hub at Swinburne University of Technology, highlighted on the inside cover of Advanced Healthcare Materials. The publication is entitled Electrical Cell Stimulation: Fabrication of a Biocompatible Liquid Crystal Graphene Oxide–Gold Nanorods Electro‐ and Photoactive Interface for Cell Stimulation.
This work outlines the deposition of graphene oxide/gold nanorod composite surfaces for the growth of neuronal cells and utilized the air plasma reactor at the ANFF-Vic Biointerface Engineering Hub to make the substrates more hydrophilic prior to the graphene oxide coatings.
Daniela is a PhD student at Swinburne University of Technology working as part of the ARC Centre of Excellence for Electromaterials Science. This paper is the first from Daniela’s PhD. Daniela has also received a commendation for this article in Swinburne’s 2019 Faculty of Science Engineering and Technology – Higher degree by research awards.
Probing in vitro cells
Scientists from the ARC Training Centre in Biodevices at Swinburne University developed a microscale multi-electrode array device (MEA) as a tool that probes the electrical properties of adherent single cells to identify their biological characteristics.
Monitoring cellular parameters in vitro is a fundamental requirement at the core of cell biology and impacts all the medical field and beyond. This technology was investigated for its potential to be used to test cell characteristics produced for cell-based therapies and reduce the cost related to their production.
The research project was conducted by Dr Steve Beguin under the supervision of Prof. Sally McArthur and in collaboration with industry partner MiniFAB. The facilities at the Melbourne Centre for Nanofabrication were extensively used by the researchers to develop a new method to manufacture microscopic electrodes that enabled high resolution and high-quality measurement of single cells in a culture of human stem cells.
The exceptionally flat topography of the microelectrodes allowed the tight cell-substrate sealing necessary to perform the measurements, which outperformed previously reported sealing resistance by 10 – 1,000-fold and allowed to directly measure the specific capacitance of the cell plasma membrane.
The project was one of the 10 PhD in Technology Innovation completed with industry in the ARC Training Centre in Biodevices at Swinburne.

As CEO of ANFF, Dr Griffiths will provide leadership and oversight to the eight ANFF nodes that are spread across Australia. Based primarily in Brisbane, QLD, Dr Griffiths will work with the ANFF team to ensure that ANFF and the 500+ micro and nanofabrication capabilities in its open access portfolio continue to enable ground-breaking research.
Publication of the year announced
MCN-enabled research published by Professor Qiaoliang Bao and colleagues at the ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) has been selected as the ANFF-VIC Publication of the Year, following an internal selection process.
The team has, for the first time, demonstrated a bizarre behaviour of light that could enable ultra-efficient optoelectrical devices and superfast transmission of information.
The team were working with van der Walls (vdW) materials – a class of materials that feature many weakly-bound layers of atoms – and a hybrid particle called a polariton – a particle of light (a photon) which is bound to a particle of vibrational energy (a phonon).
The paper, In-plane anisotropic and ultra-low-loss polaritons in a natural van der Waals crystal, was chosen as the winner by ANFF-VIC’s selection panel due to its impact, pioneering nature and level of engagement with MCN. All papers that were published in 2018 that correctly acknowledged ANFF-VIC were eligible for selection.

Dr David J. Garrett
Senior Research Fellow – University of Melbourne
Dr David Garrett’s career has been aimed at overcoming the limitations of neural interface technology using carbon materials, resulting in a series of patents and more than 40 papers within eight years.
In 2015, Dr Garrett founded a start-up in Canada, based around commercialising a retinal prosthesis developed in his early career.
Dr Garrett will be focused on how to translate devices that harness the properties of nanometre-thick layers of diamond to industrially relevant applications, investigating both the abilities of these devices, and the way they connect with the outside world.
As such the team will be heavily using MCN’s diamond deposition suite, featuring two Seki MPCVD systems that are used for growing ultra-high purity and nitrogen vacancy diamond, or for growing boron-doped diamond.
Dr Ranjith Unnithan
Senior Lecturer – University of Melbourne
Dr Ranjith Unnithan’s research areas span CMOS image sensors, electronic sensors for biomedical applications, thermal image cameras and nanophotonic engineering.
In addition to publishing a string of high-impact papers, Dr Unnithan has demonstrated a talent for commercialising technologies, having won four innovation awards and co-founding Hort-Eye Pty Ltd – a precision drone sensing company – with a team from the University of Melbourne.
Dr Unnithan will be working to improve the ways in which nanostructures are incorporated with electrical devices such as CMOS image sensors. He aims to improve the fabrication process of these nanostructures to allow them to be created directly onto a sensor, which would reduce the size, weight and power consumption of these devices compared to traditional technologies.
Nanostructures are of interest to imaging applications as they can be used to tune a sensor to particular bands of the light spectrum, making them incredibly useful when trying to collect as much information about a field-of-view as possible. However, current methods to create the structures involve the use of heat, vacuums or plasmas which can reduce the sensitivity of the sensor instead of enhancing it – fabrication issues Dr Unnithan hopes to overcome using novel manufacturing processes.
Dr Unnithan’s project will be reliant on MCN’s high-resolution lithography systems, including the NanoFrazor which uses a heated cantilever tip to create structures with a resolution of ~10nm.
Professor Peter Kingshott
Department Research Director – Swinburne University of Technology
Professor Peter Kingshott has built an international profile in the multidisciplinary field of biointerface science – his expertise extends into nanomaterials, colloid and surface science, biomaterials, biomedical engineering, and regenerative medicine.
