About Us


The Duan group in Biomedical Engineering at CUHK is interested in innovative biomedical applications based on the cutting-edge optogenetic method.  We focus on designing and developing optical strategies to remotely and non-invasively control critical intracellular processes,  such as signaling pathways and organelle activities. These novel strategies will obtain unprecedented spatial and temporal resolution, and provide promising approaches to drug discovery and gene therapy.

Our paper on light-inducible deformation of mitochondria is now available on Cell Chemical Biology

We can use light to stretch mitochondria in living cells.


Our Opto-TrkB work is accepted by Journal of Molecular Biology!

Congratulations to all the authors!
