Summary
Decode Neuro-Mechanobiology:mechanosensitive ion channels in proprioception. Human bodies are densely covered with numerous mechanosensory neurons that provide us with the sense of touch and pain. However, the molecular force sensors remain poorly identified. This project aims at defining the fundamental roles of mechanosensitive ion channels to sense and respond to various mechanical stimuli, and how their responses may encode mechanical cues.The ultimate goal is to provide a fundamentally new ....Decode Neuro-Mechanobiology:mechanosensitive ion channels in proprioception.

This project aims at defining the fundamental roles of mechanosensitive ion channels to sense and respond to various mechanical stimuli, and how their responses may encode mechanical cues.The ultimate goal is to provide a fundamentally new understanding of proprioception and motion sensing. The new multimodality approach generated in this project is expected to evolve as a national facility for neuro-mechanobiology, and future research may lead to the inspiration of novel bionic sensor design and brain-computer interface for future neuroengineering industry.Read moreRead less
A Multi-Optrode Array for Closed-Loop Bionics. We will design, implement and characterise a disruptive multi-channel optrode array (MOA) to record and stimulate excitable living tissue. The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue.

By employing light for communication with optrodes, this new approach alleviates many of the wiring, packaging and encapsulation issues associated with existing devices. Computational modelling and in vitro testing in cardiac tissue and retinal neurons will demonstrate the utility of the MOA to sense and control electrical activity.Read moreRead less

Whereas current approaches are limited to defining the external geometry, this technology will permit the organization of the internal structure as well, with the potential to do so at the scale of individual cells. Achieving this has important applications in bioprinting human tissues and additive manufacturing. This is based on the manipulation of particles and cells using holographic acoustic fields controlled by patterned light. This is compared to current acoustic patterning approaches are mostly limited to static simple geometric arrangements and lack the flexibility to produce arbitrary, rapidly changing fields that enable the fabrication of complex structures.
