Nanofabulous Seminar: From bioinspired structure formation to particle-based metamaterials
Metallic nanoparticles offer a range of interesting optical and electronic effects. A prominent example is the localized surface plasmon resonance (LSPR) due to resonant excitations of vibrations of the particles’ free-electron cloud by light. Due to the LSPR, plasmonic nanoparticles provide excellent means for controlling electromagnetic near-fields at optical frequencies, which has led to a broad range of applications in various field such as surface enhanced spectroscopy, light harvesting or photonics.
While much research has been dedicated to understanding nanoparticle synthesis and tailoring their LSPR on the single particle level [1-3], ordering particles on different length scales opens another powerful avenue towards optical and electronic functionality, as novel collective plasmonic excitations are occurring due to plasmonic coupling effects.
We focus on achieving such ordered particle arrays via assembly approaches. Colloidal self-assembly indeed succeeds in achieving well-defined colloidal clusters [4] and surface assemblies [5] in which coupling effects can be controlled. Especially when combined with biomimetic surface structuring, large area assemblies are feasible. We discuss the underlying physico-chemical principles of the assembly process and the arising plasmonic coupling effects [6,7]. Finally, we highlight perspectives for taking this assembly principle to meta-surfaces with high field enhancement and/or ultra-high circular dichroism [6, 8].

Nanofabulous Seminar: Hot tip nanoengineering: 30 years and counting
Abstract
Soon after the first publication in 1985 of the atomic force microscope (AFM) attempts were made to extend AFM-based surface probing from microscopy to lithography. In this talk, I will start by giving some background how heated AFM probes were initially designed and microfabricated that led to today’s advanced thermo-mechanical probe design. The paper will then review some of our own work in t-SPL writing and pattern transfer, as well as our recent work on functional material, including silk and 2D materials. Download flyer here.

BEAMeeting Brisbane 2023 – Technical Workshop & Discussion
The BEAMeeting is a technical exchange and upskill platform for the microfabrication community focused on e-beam, laser, process correction, and metrology. We have the privilege to invite GenISys, who specialises in software solutions for direct write lithography and automated SEM analysis to co-establish the first of its kind BEAMeeting in Australia, hosted by The University of Queensland.
The talks will be focused on research works in the Australian universities and start-ups on the use of advanced manufacturing in lithography, with topics of nanophotonics, MEMs, quantum sensors and automated metrology.

Nanofabulous Seminar: Photonic Chip Frequency Combs: Australian Made Technologies for Measuring Almost Anything
Optical frequency combs were invented near the end of the 20th century and have revolutionised precision measurement – particularly the measurement of time with optical atomic clocks. Their significance was recognised with the award of the 2005 Nobel Prize in physics, but since then have remained largely within sophisticated laboratories. Recent advances have made it possible to realise optical frequency combs in the form of micro-chips which can be manufactured cheaply, are compact and efficient. These advances open the possibility to use optical frequency combs in a much wider range of applications outside the laboratory with the potential to transform our every-day lives.
This seminar will introduce optical frequency combs, explain how they are used for precision measurement and describe emerging approaches that can be used to achieve optical frequency comb systems as micro-chips. The talk will present an outlook for the diverse areas of application where combs might have transformative impact spanning high-speed data communications, machine learning, seismology, biomedical imaging, monitoring civil infrastructure and the environment, and even searching for life on other planets.
Particular emphasis will be placed on the role of the spectacular ANFF facilities that are enabling us to take a world leading position in this high technology research area – and that will be invaluable in taking the next step to translate these technologies to industry and real-world end-users.

Nanofabulous Seminar: micro and nanotechnologies to direct mesenchymal stromal cell fate for tissue regeneration
Mesenchymal stromal cells (MSCs) show great promise for a wide range of applications including treating graft-vs-host disease, rheumatoid arthritis and cardiovascular diseases, as well as in tissue-engineering. This can be attributed to the direct differentiation of MSCs into the cells that form tissues such as bone or cartilage, or the activity of the factors that MSCs secrete which can have powerful regenerative properties.
MSC properties are tightly regulated by cues from their surrounding microenvironment, including physical cues such as substrate mechanical properties, ligand presentation and architecture. Bioengineered systems therefore gave a huge role to play in building essential understanding of how the cells respond to different physical cues, as well as in developing new technologies that harness these effects to promote tissue repair. Our research investigates the effects of physical stimuli on the properties and function of MSCs, including effects of substrate mechanical properties, surface micro and nano-topography and changes from 2D to 3D. We then apply this knowledge to improve the design of systems for MSC differentiation and tissue formation, for example, by delivering microRNA:nanoparticle complexes to modulate mechanosensitive signalling pathways in MSCs encapsulated in hydrogels and promote osteogenesis for bone tissue engineering.

Nanofabulous Seminar: Nature meets Nanotechnology: Development of Novel Bio-composites from Renewable Resources
Proteins form the very basis of life. They regulate various activities in all known organisms, from replication of the genetic code to transporting oxygen, and are responsible for regulating the cellular machinery and determining the phenotype of an organism.
From a material science point of view, proteins can serve as excellent building blocks for developing new structures, composites, and novel materials. In this talk, I will cover some of our efforts in this direction, demonstrating our bottom-up technology to form various new materials, including light-emitting devices, photothermal materials, smart-wound dressing, antibacterial coating, heavy-metal sorption materials, and more. The role of Jellyfish, an important renewable resource for many of our applications, will be discussed.

Nanofabulous Seminar: Single-electron tunneling through dopants in thin-Si devices
Daniel Moraru has been working on the development of a unique research direction for semiconductor nanoscale devices, aiming for atomic- and molecular-scale electronics by utilizing dopant atoms (or dopant clusters as “molecules”) in silicon. Through such research, he and his group have been contributing to the advancement of a field coined as “dopant-based electronics”. In his lab, research is performed from different perspectives, from first-principles simulations of atomistic effects to Si nanodevice fabrication and electrical characterization at the level of single-electron tunneling.
