“…[58] These results are in qualitative agreement with our previous data for continuous ETPTA inverse films. [9,15] Thus, a specific respond of the ETPTA inverse micropatterned PhCs to alcohols enable to consider them as alcohol sensors.…”

“…[3][4][5][6] The traditional visual PhC sensor is based on a change in the crystal parameter or effective refractive index under the influence of external factors. [7][8][9][10][11][12] In particular, polymeric materials containing PhC structures can provide a dynamic optical response to environmental variables [13][14][15][16][17][18] such as humidity, pH, and ionic strength in the readily recognizable visible color range and thus have emerged as promising materials for sensing. At the same time, synthetic opals and inverse opals are very promising materials for producing substrates for surface enhanced Raman scattering (SERS).…”

A simple and frugal method for fabricating inverse micropatterned photonic crystal (PhC) films aimed at miniaturization and multiplexing of opaline PhCs is described. First, highly uniform micropatterned synthetic opal structures in the form of periodic stripes are formed via stick‐slip motion of the meniscus during SiO2 colloid solution evaporation. The prepared opal structures are then used as templates to produce inverse stripe patterned films with highly uniform colors via photopolymerization of ethoxylate trimethylolpropane triacrylate (ETPTA) photocurable resin. Local reflectance spectra are recorded to prove the PhC properties of the inverse stripes, and peaks over 40% associated with the first photonic stop band are observed. The readily fabrication process suggested here is an important step toward the development of many applications that can pave the technical road map for the next wave of innovations and breakthrough in PhCs for sensing. In particular, the resulting structures can be used as PhC arrays containing a line of periodically repeating sensor strips capable to detect the content of alcohols in water.

“…[141] Solvent/water mixtures and their concentrations are particularly well studied for photonic crystal detection systems. [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.…”
