Nanomaterials have been applied in healthcare applications such as cancer imaging, lymph node mapping and brain diseases therapy. These nanomaterials can be engineered to serve as a platform for challenges in highly sensitive optical diagnostic tools, biosensors, and guided imaging and therapy. The versatility of nanomaterials may provide the keys to improve diagnostics and therapy of human diseases. In this talk, we will highlight the use of nanomaterials with different sizes, compositions, and shapes for nanomedicine applications. This talk is intended to promote the awareness of past and present developments of nanomaterials in biomedical fields, the potential toxicity of nanomaterials, and the approaches to engineer new types of safe nanomaterials, whereby encouraging researchers to think about exciting and promising biophotonic and nanomedicine applications with nanomaterials in the future.

The past decade has seen accelerated progress in III-V semiconductor infrared photodetector technology. The advent of the unipolar barrier infrared detector device architecture has in many instances greatly alleviated generation-recombination (G-R) and surface-leakage dark current issues that had been problematic for many III-V photodiodes. Meanwhile advances in a variety type-II superlattices (T2SLs) such as InGaAs/GaAsSb, InAs/GaSb, and InAs/InAsSb, as well as in bulk III-V material such as InGaAsSb and metamorphic InAsSb, have provided continuously adjustable detector cutoff wavelength coverage from the short wavelength infrared (SWIR) to the very long wavelength infrared (VLWIR). The confluence of these developments has led to a new generation of versatile, cost-effective, high-performance infrared detectors and focal plane arrays based on robust III-V semiconductors, providing a viable alternative to HgCdTe (MCT).

Circulating exosomal miRNA represents a potentially useful class of bloodborne biomarkers for cancer. We present the initial proof-of-concept of an approach in which gold nanoparticle tags are prepared with thermodynamically optimized nucleic acid toehold probes that displace a oligonucleotide and reveal a capture sequence that is used to selectively pull down the target-probe-nanoparticle complex to a photonic crystal (PC) biosensor surface. By matching the surface plasmon resonant wavelength of the nanoparticle tag to the resonant wavelength of the PC nanostructure, the reflected light intensity from the PC is dramatically and locally quenched by the presence of each nanoparticle.
The talk described the optical operating principles of Photonic Resonator Absorption Microscopy (PRAM), the thermodynamic design of DNA toehold probes, and our first results demonstrating the detection limits, selectivity, and dynamic range of the assay.
Abstract: In this presentation, Garrett provides an overview of how two scientists from the University of Vienna stumbled upon an enabling technology, born from fundamental research in the burgeoning field of cavity optomechanics, and made a successful transition from academia to industry. The fruit of this endeavor is “Crystalline Mirror Solutons,” or CMS, a photonics start-up commercializing high-performance optics for laser-based precision measurement and manufacturing systems. Here, Garrett outlines the key elements that led to their successes, including the conception of the underlying technology, as well as the supporting infrastructure and funding organizations that ultiately assisted in bringing this idea out of the laboratory and onto the
Bio: Dr. Garrett D. Cole, Co-Founder of Crystalline Mirror Solutions (www.crystallinemirrors.com), obtained his PhD in Materials from the University of California, Santa Barbara in 2005. Since completing his doctorate, he has held positions ranging from the first employee of a high-tech startup (Aerius Photonics LLC, now FLIR Electro-Optical Components), to a postdoctoral position at Lawrence Livermore National Laboratory, a Marie Curie Fellow of the Austrian Academy of Sciences, and, prior to leaving to found CMS, an assistant professor in the Faculty of Physics at the University of Vienna. In the course of his research career, Dr. Cole has co-authored 2 book chapters and published more than 50 journal articles and conference proceedings including papers in Science, Nature, Physical Review Letters, and the Proceedings of the National Academy of Sciences. Leveraging his expertise in micro- and nanofabrication, tunable lasers, and cavity optomechanics, Dr. Cole developed the proprietary substrate-transfer process at the heart of Crystalline Mirror Solutions and, along with Professor Markus Aspelmeyer, co-founded the venture in February 2012.
Abstract: Success in a photonic startup company requires constant attention to the balance between risk and opportunity. These risk / opportunity decisions involve many different areas, technical, marketing, financial, organizational and psychological, among others. Some of these decisions are very specific to photonic startup issues but the balance of opportunity and risk touches on a broad range of aspects of life, of course.
This presentation discussed the general nature of risk and opportunity and from these general ideas will then derive recommendations for effective risk management methods in photonic startups. The presenter did this through examples drawn from his own experience and from the experience of others that have influenced him strongly
Bio: Dr. Daniel Renner received a Ph.D in Opto-Electronics from the University of Cambridge in England. This has been followed by 37 years of industrial experience, where he has been deeply involved with the development, manufacturing and commercialization of complex photonic devices and systems used in communication, sensor and industrial applications. His experience spans both the technical and the commercialization aspects of photonic products, having led activities in many areas, including technology and product development, identification of new business areas, introduction of new products, marketing and sales. Through this experience he has gained a respectful appreciation for the critical importance of effective business risk management.

Abstract: The excitement of nanowire research is due to the unique electronic and optical properties of these nanostructures. Both axial and radial heterostructure nanowires have been proposed as nano‐building blocks for the next generation devices, which are expected to revolutionise our technological world. The unique properties stem from their large surface area‐to‐volume ratio, very high aspect ratio, and carrier and photon confinement in two dimensions. These nanowires are usually grown by the so‐called vapor‐liquid‐solid mechanism, which relies on a metal nanoparticle to catalyze and seed the growth. An alternative technique to grow the nanowires is by selective area growth technique, where a dielectric mask is first patterned on the substrate prior to growth. In this talk, I will present an overview of compound semiconductor nanowire research activities at The Australian National University. The optical and structural properties of binary and ternary III‐V nanowires including GaAs, InGaAs, InP and GaAsSb nanowires grown by metal‐ organic vapour phase epitaxy will be presented. Various issues such as tapering of the nanowires, compositional non‐uniformity along nanowires, crystal structure, carrier lifetime and polarization effect will be discussed. I will also present our results of III‐V nanowires grown on Si substrates which are of great interests for the integration of nano‐optoelectronic devices on Si platforms. Our results of enhancing the quantum efficiency of nanowires by using plasmonics are promising to improve the performance of nanowire devices. Finally, the results from our nanowire lasers, photodetectors, solar cells and photoelectrodes for water splittng will be presented.
