Recent progress in low‐swellable polymer‐based smart photonic crystal sensors

“…Inverse opal polymers are essentially porous materials, and the connected macropores are particularly suitable for the design and construction of micro-reactors due to the outstanding mass transfer. [21,192,262,263] The properties of inverse opal-derived SPCSs mainly depend on the chemical and physical properties of the polymer skeleton. They are generally films with good mechanical properties.…”

Core–Shell Silica Nanoparticle-Based Barcodes Combined with a Hybridization Chain Reaction for Multiplex Quantitative Detection of Bacterial Drug-Resistance Genes

“…19,20 For a known photonic material, its optical structural color is related to the periodic nanoscale. 21 Therefore, they can have different structural colors as encoding elements by adjusting the size of the periodic nanostructure. PhCs possess excellent encoding stability since they do not suffer from photobleaching or fluorescence background interference.…”

“…A variety of coding technologies have been developed to expand the field of suspension barcodes, such as organic fluorescent, , quantum dot, graphic barcode, and photonic crystal (PhC) barcodes . PhCs are optical materials with the photonic band gap induced by periodic nanostructures. , For a known photonic material, its optical structural color is related to the periodic nanoscale . Therefore, they can have different structural colors as encoding elements by adjusting the size of the periodic nanostructure.…”

Asymmetrical Optical Response of Opal Photonic Crystals with Graded Thickness

“…9,10 Extensive reviews of the characteristics which underpin these structures, and their applications are provided elsewhere. 11,12 In top-down fabrication methods where compounds are formed layer by layer, these graded thickness PhCs can be designed easily in 1D, 2D and 3D. [13][14][15] In this case, the thickness gradient is parallel to the growth direction that induces a graded refractive index contrast which shifts the position of the PBG.…”
