“…Compared with 3D-PCs, monolayer-ordered arrays of two-dimensional photonic crystals (2D-PCs) can be easily fabricated and precisely controlled . 2D-PCs have been intensively investigated in the field of sensors, − displays, and solar cells , because of the simple preparing procedure, low cost, high production efficiency, and easy functionalization . When the incident light located in the 2D-PC plane interacts with the ordered arrays, the photonic band gap of 2D-PCs will limit the propagation path of light.…”

Responsive photonic crystals (PCs), which can adjust structural colors in response to external stimuli, show great potential applications in displays, sensors, wearable electronics, encryption, and anticounterfeiting. In contrast, conventional structure-intrusive adjustment manners that external stimuli directly interact with the ordered arrays may lead to structural damage or longer response time. Here, a noninvasive adjustment of the structural colors of twodimensional (2D) PCs (2D-PCs) is explored based upon diffraction theory. Sealed 2D-PCs and 2D inverse opal photonic crystal (IOPC) flexible devices are prepared. They are highly transparent in air but immediately exhibit intense viewing angle-dependent structural colors after being dipped in water. The mechanism of transparent-iridescent immediate transformation is explained by Bragg's law. The design mechanism is examined by numerical simulation and spectral shifts in different external media. We demonstrate its applications in the fields of information encryption and anticounterfeiting by using the transparent-iridescent immediate transformation of sealed 2D-PC patterns and 2D IOPC free-standing films sealed on the product surface. Because of the strong contrast between transparency and intense iridescence, reversible and immediate transformation, and durability, sealed 2D-PCs and 2D IOPC flexible devices designed by the noninvasive adjustment strategy will lead to a variety of new applications in displays, sensors, wearable electronics, encryption, and anticounterfeiting.

“…Inverse opal MIP films, which use colloidal crystals as templates for the morphology of their pore structure, have been reported for the fabrication of label-free photonic sensors [8,9]. The methodology relies on the optical properties of the film, in particular the shift of the reflectance peak wavelength that occurs after target molecules are adsorbed [10,11]. Pesticide detection by photonic MIPs was reported for several pesticides, including imidacloprid [12][13][14], atrazine [15,16], 2,4-D [17], parathion [18], and methyl paraoxon [19].…”

A photonic sensor based on inversed opal molecular imprinted polymer (MIP) film to detect the presence of chlorantraniliprole (CHL) residue in tomatoes was developed. Acrylic acid was polymerized in the presence of CHL inside the structure of a colloidal crystal, followed by etching of the colloids and CHL elution. Colloidal crystals and MIP films were characterized by scanning electron microscopy and FT-IR, confirming the inner structure and chemical structure of the material. MIP films supported on polymethylmethacrylate (PMMA) slides were incubated in aqueous solutions of the pesticide and in blended tomato samples. The MIP sensor displayed shifts of the peak wavelength of the reflection spectra in the visible range when incubated in CHL concentrations between 0.5 and 10 μg L −1 , while almost no peak displacement was observed for non-imprinted (NIP) films. Whole tomatoes were blended into a liquid and spiked with CHL; the sensor was able to detect CHL residues down to 0.5 μg kg −1 , significantly below the tolerance level established by the US Environmental Protection Agency of 1.4 mg kg −1 . Stable values were reached after about 30-min incubation in test samples. Control samples (unspiked processed tomatoes) produced peak shifts both in MIP and NIP films; however, this matrix effect did not affect the detection of CHL in the spiked samples. These promising results support the application of photonic MIP sensors as an economical and field-deployable screening tool for the detection of CHL in crops.

“…Therefore a novel pretreatment that has high selectivity, stability, simple operation and good antiinterference ability for glycoprotein tumor biomarkers is important to solve these drawbacks for antibody-free analysis. 4 Molecular imprinting is an attractive technique to prepare highly selective polymers which have synthesized binding sites and can rebind specically with a template molecule. The obtained molecularly imprinted polymers (MIPs) are stable, robust, and low cost.…”
