    1. 30. Engineering of Plasmoinc Nanomaterials for Surface-enhanced Raman Scattering-based in vitro Cancer Diagnosis
      Prof. Yuling Wang (Macquarie University)

      COMMAD: Biomedical integrated circuits and implantable devices
      Talk (preferred)

      As plasmonic nanomaterials play critical roles in facilitating surface-enhanced Raman scattering (SERS) applications in cancer diagnosis, We thus have developed a few strategies to engineer functional plasmonic nanomaterials for SERS-based in vitro cancer diagnostic applications.

    2. 249. Fluorescence-based Fibre Optic Sensor for Hydrogen Sulphide Detection

      Talk (preferred)

      A fluorescnece-based fibre optic sensor has been developed to detect hydrogen sulfide. Optical fibre functionalized with HS-sensitive fluorophore shows an increase in the fluorescence emission upon reaction with HS, the similar behaviour to when fluorophore is dissolved in the solution.

    4. 319. Nitrogen-doped ultrananocrystalline diamond electrodes for photostimulation of human mesenchymal stem cells

      Talk (preferred)

      In this work, nitrogen-doped ultrananocrystalline diamond (N-UNCD) electrodes are characterised for light-based cell stimulation. We utilise ultraviolet photoelectron spectroscopy (UPS) to probe the photocurrent mechanisms of these photoelectrodes, which are then applied for the stimulation of human mesenchymal stem cells.

      COMMAD: Biomedical integrated circuits and implantable devices
      Talk (preferred)

      In this work, we report our group’s recent efforts to create flexible and biocompatible neural interfaces. We combine soft carbon-based organic semiconductors and nanoscale science to print innovative bioelectrodes from functional nanoparticles that enable optical neurostimulation without requiring external power.

    6. 490. Semiconducting Polymer X-ray Detectors with Non-Fullerene Acceptors for Enhanced Stability: Towards Printable, Flexible, and Tissue Equivalent Devices
      Jessie Ann Posar (University of Sydney)
      16/12/2022, 10:15
      AIP: Biomedical and Medical Physics
      Talk (preferred)

      A novel tissue-equivalent organic x-ray detector was fabricated from polymer donor P3HT and non-fullerene acceptor o-IDTBR exhibiting superior optoelectronic properties for high operating efficiencies under x-rays without bias. Insights into radiation-induced damage mechanisms enabled material modifications to improve device stability.
