Investigation of optical images in inverse opal photonic crystal films for sensing applications; a non-destructive method

Biomarkers and optical based biosensors in cardiac disease detection: early and accurate diagnosis

“…PCs like inverse opals and PC bers are now being extensively applied in bio-sensing investigations. 103,104 In PC structures, the nano-crystals were periodically repeated in one, two, or three directions each of them having different dielectric constants. Inverse opals with the PC structures are commonly designed by 3D ordered polymer microspheres using the inltration of a lling material precursor like TiO 2 , ZnO, SiO 2 , and polymers in the holes of opaline arrays.…”

Many Facets of Photonic Crystals: From Optics and Sensors to Energy Storage and Photocatalysis

“…[139,142,143] More recently, some works have focused on developing photonic crystal sensors which offer a visual structural color indicator for the presence and concentration of particular solvents, [144][145][146] with even the optical image intensity and peak absorbance linked to ethanol concentrations for SiO 2 IOs. [147] Similarly, carbon IOs have demonstrated promising oil sensing capabilities with excellent response times and reversibility of the photonic stopband. [148] The visual structural color of oil/gasoline and ethanol/gasoline mixtures has been exploited to indicate mixture concentrations in SiO 2 IO coated with hydrophobic fluoroalkylchlorosilanes.…”
