摘要：
Chemiluminescence behaviour in the core region of water/oil/water double emulsion droplets with cholesteric liquid crystalline (CLC) middle phase (CLC core- shell microcapsules) was demonstrated. We successfully fabricated CLC core- shell microcapsules containing an aqueous luminol solution as the inner phase using a microfluidic device, in which the helical axis of the CLC phase is normal to the surface. The CLC core- shell microcapsules proved to be a plausible candidate for highly sensitive H2O2 sensors because of the omnidirectional photonic structures of the CLC phase.
