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.
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.
This work explores the feasibility of simulating heat transfer for a single laser irradiated retinal cell in 3D, with a focus on a novel methodology to represent laser intensity decay for complex structures with sub-micron resolution.
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.
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.
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.
