Abstract
Photonic crystals(PCs) are periodic dielectric-structure materials with a photonic bandgap for electromagnetic waves.By combining stimuli-sensitive material with photonic crystals,the formed photonic crystals can respond to the external environments,which are named as responsive photonic crystals.Being a new branch of photonic crystals,responsive photonic crystals have attracted considerable attention as applications in sensors,biomedicine,clinical assay,sensor etc in recent years.According to difference of external environments,responsive photonic crystals can be briefly classified into three different types,chemical responsive photonic crystals,physical responsive photonic crystals and biological responsive photonic crystals.In this article,we mainly review the progress in chemical responsive photonic crystals in recent years,including metal ion-responsive,pH-responsive,redox-responsive,glucose-responsive and photochemistry-responsive photonic crystals.
