This project aims to engineer nanomaterials by utilising gold nanochemistry and neural tracing capabilities of plant-based, nontoxic proteins. In a significant departure from current nanomaterials being developed, functionalising nanoparticles with the tracers enable them to undergo path-specific axonal retrograde transport, transneuronal transport, and anatomical tract flow to bypass the blood-brain barrier. Microfluidics will be used to characterise the neuronal activities of the synthesised nanoconjugates of different sizes and compositions to understand their bio-interactions with axons, synapses, and neuromuscular junctions. The results will lead to a new class of functional nanomaterials as well as cell-based functional assays.Read moreRead less

This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale. Traditional electromechanical devices based on ferroelectric materials including position sensors, mechanical actuators, and ultrasonic transducers rely on bulk form. As technology moves toward integrated functionalities, future electro-mechanical materials need to be scaled down to thin film form. Currently, doing this induces mechanical constraints that dramatically suppress the electromechanical response. Using this approach one layer relieves this mechanical constraint while the other gives a giant electromechanical response, providing a pathway for future functional devices. Read moreRead less
