The structural color change by temperature, chemicals, electric field, and magnetic field.[2] The ability to change the color in response to a suitable stimulus exhibit behavior that are forming the basis of numerous passive and active electro-optic applications.[3] Motivated by this opportunity, we recently produce polymeric micro particles templated from CLC by using photolithography and microwell molding methods on the purpose of sensor applications. This study includes the synthesis and characterization of polymeric micro particles synthesized from cholesteric LC templates, including their shape, size, polydispersity, internal structure, and optical properties. Finally, response of CLC templated polymeric micro particles to volatile organic compounds was tested for sensor applications.
