Photonic solid-state cholesteric liquid crystal (CLCsolid) droplets intertwined with a poly(acrylic acid) (PAA) network that had an interpenetrating polymer network (IPN) structure (referred as photonic IPN CLCsolid–PAA droplets) were used as individual sensors in the dots of a PAA-patterned array film after functionalization via immobilization of the receptors and a metal-ion treatment. The photonic IPN CLCsolid–PAA droplets in the PAA-patterned array film were pH-responsive with an observable change in the reflected central color. This “smart” property, coupled with the photonic color response, make these devices ideal photonic sensors.
