What is it about?
These photonic colloidal crystalline beads were found to possess enough structural integrity for in vivo imaging of the GI tract of live Japanese medaka. With the use of a conventional optical microscope, the gradient in the ionic strength of cationic electrolytes along the GI tract of live Japanese medaka larvae was readily revealed, with a lower electrolyte concentration in the mid-intestine (<50 mM) compared to that of the posterior-intestine (50 mM).

Why is it important?
Our results demonstrated the potential of stimuli-responsive photonic materials in bio-imaging applications.
Perspectives
We hope to show that the application of stimuli-responsive photonic band-gap materials in bio- imaging is an area worthy of exploring.
