“…C-PC has been widely used as a sacrifice template for the development of 3D microporous structures and IOs. The C-PCs elaborated in the reproducibility assay were employed for the fabrication of acrylic-based IOs (such as those used, for example, for the development of photonic polymeric sensors [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]). The obtained materials showed a violet iridescent color ( Figure 10 a); their reflectance spectrum exhibited a narrow peak (74 nm) centered at 409 nm ( Figure 10 b).…”

“…Additionally, C-PCs have been studied as sacrifice templates to create inverse opals (IO) employing inorganic, organic, metallic, and ceramic materials, which are exact inverse replicas of C-PC structures and therefore maintain their optical properties [ 15 ]. Due to the uniform and well-controlled pore sizes, ordered periodicity, and interconnected pore systems, IOs have been explored for a wide range of fields including biomedical scaffolds [ 16 ], membranes [ 17 ], solar cells, photocatalysts [ 18 ], and sensors for the detection of different compound families such as explosives [ 19 ], pesticides [ 20 , 21 , 22 ], organophosphates [ 23 , 24 ], drugs [ 25 , 26 ], antibiotics [ 27 , 28 ], and hormones [ 29 , 30 ], among others [ 31 , 32 ].…”

Photonic crystals (PCs) are nanomaterials with photonic properties made up of periodically modulated dielectric materials that reflect light between a wavelength range located in the photonic band gap. Colloidal PCs (C-PC) have been proposed for several applications such as optical platforms for the formation of physical, chemical, and biological sensors based on a chromatic response to an external stimulus. In this work, a robust protocol for the elaboration of photonic crystals based on SiO2 particle (SP) deposition using the vertical lifting method was studied. A wide range of lifting speeds and particle suspension concentrations were investigated by evaluating the C-PC reflectance spectrum. Thinner and higher reflectance peaks were obtained with a decrease in the lifting speed and an increase in the SP concentrations up to certain values. Seven batches of twelve C-PCs employing a SP 3% suspension and a lifting speed of 0.28 µm/s were prepared to test the reproducibility of this method. Every C-PC fabricated in this assay has a wavelength peak in a range of 10 nm and a peak width lower than 90 nm. Inverse-opal polymeric films with a highly porous and interconnected morphology were obtained using the developed C-PC as a template. Overall, these results showed that reproducible colloidal crystals could be elaborated on a large scale with a simple apparatus in a short period, providing a step forward in the scale-up of the fabrication of photonic colloidal crystal and IO structures as those employed for the elaboration of photonic polymeric sensors.

Chemical contaminants in food generally include natural toxins (mycotoxins, animal toxins, and phytotoxins), pesticides, veterinary drugs, environmental pollutants, heavy metals, and illegal additives. Developing a low-cost, simple, and rapid detection technology for harmful substances in food is urgently needed. Analytical methods based on different advanced materials have been developed into rapid detection methods for food samples. In particular, photonic crystal (PC) materials have a unique surface periodic structure, structural color, a large surface area, easy integration with photoelectronic and magnetic devices which have great advantages in the development of rapid, low-cost, and highly sensitive analytical methods. This review focuses on the PC materials in the view of their fabrication processes, functionalized recognition components for the specific recognition of hazardous substances, and applications in the separation, enrichment, and detection of chemical hazards in real samples. Suspension array based on three-dimensional PC microspheres by droplet-based microfluidic assembly is a great promising and powerful platform for food safety detection fields. For the PCs selective analysis, biological antibodies, aptamers, and molecularly imprinted polymers (MIPs) could be modified for specific recognition of target substances, particularly MIPs because of their low-cost and easy mass production. Based on these functional PCs, various toxic and hazardous substances can be selectively enriched or recognized in real samples and further quantified in combination of liquid chromatography method or optical detection methods including fluorescence, chemiluminescence, and Raman spectroscopy.

Using polystyrene two-dimensional photonic crystal as template, gatifloxacin (GTFX) as imprinting molecule, methanol as solvent, acrylic acid as functional monomer, ethylene glycol dimethyl acrylate as crosslinking agent and 2,2diethyloxyacetophenone as initiator, after UV initiation polymerization the GTFX molecularly imprinted two-dimensional photonic crystal hydrogel (GTFX-MIPCH) sensor was prepared. The response performance of the hydrogel was investigated by measuring the diameter change of the Debye ring. The experimental results showed that the prepared GTFX-MIPCH has a sensitive response to GTFX. When the concentration of GTFX increases from 0 to 1 × 10 −4 mol L −1 , the diameter of the Debye ring decreases by 8.50 mm, the corresponding particle spacing increases by 29.1 nm, and the color of the sensor changes from purple to orange. Also there was a linear relationship between the change of particle spacing (Δd) and the logarithm of GTFX concentration (lg c) in the range 10 −12 -10 −6 mol L −1 . It is noteworthy that the limit of detection of GTFX-MIPCH is as low as 10 −14 mol L −1 . In addition, in a solution of GTFX analogues enrofloxacin, levofloxacin, ciprofloxacin and norfloxacin, the change of particle spacing of the GTFX-MIPCH sensor is 13.3, 11.6, 11.1 and 10.3 nm respectively, indicating that GTFX-MIPCH has good specific recognition ability for GTFX. Moreover, GTFX-MIPCH shows good reusability and can also be used for the detection of GTFX in water samples. This GTFX-MIPCH can achieve a visual detection effect on GTFX through the Debye ring and color change.
