Summary: In comparison with molecularly imprinted photonic hydrogel, surface molecularly imprinted photonic hydrogel is more competitive as a molecular sensor due to presence of molecular recognition sites on its surface. However, the construction of surface molecularly imprinted photonic hydrogel sensors is still challenging. In this study, we report the construction of such sensors using poly (styrene-acrylic acid) colloids with carboxyl groups, which can readily bind imprinted molecules through hydrogen interaction. The constructed sensors exhibit high sensitivity, rapid response speed, and good selectivity, and show good sensing performance even in commercial milk.

Summary: In this study, a photonic crystals (PhCs) sensor with water retention and antifreezing properties was developed for visual hazardous gases sensing at low temperature. The sensor responded to hazardous gases by changing its reflection wavelength and visible structural color. The sensor also showed great water retention and antifreezing properties at low temperatures, and maintained its response to hazardous gases even after freezing and testing at extreme temperatures.

Summary: This study developed two partially base complementary aptamer-functionalized two-dimensional photonic crystal hydrogels for detecting thrombin in human plasma. The sensor achieved sensitive and selective detection of thrombin by measuring the particle spacing changes caused by the swelling of the hydrogel upon thrombin binding. The optimized sensor showed linear response over the concentration range of 1-500 nM with a detection limit of 0.64 nM.

Summary: In this study, we demonstrate fiber optic sensors with temperature compensation for accurate measurement of ethanol concentration in aqueous solutions. The sensors consist of two photonic crystal fiber-tip sensors, one for measuring ethanol concentration and the other for independent measurement of temperature. By combining the information from the two sensors, the effect of temperature on concentration measurement can be compensated for, resulting in more accurate estimations of ethanol concentration.
