Summary: Sensitive, rapid, and continuous detection of hydrogen peroxide (H2O2) is important in many systems. However, current H2O2 sensor technologies are costly, lack specificity, and are bulky, making continuous monitoring challenging. In this study, a highly flexible hydrogel-based electrochemical sensor was developed for reliable and ultrasensitive detection of H2O2 in liquid environments.

Summary: A responsive photonic hydrogel was prepared by embedding a three-dimensional photonic crystal into an amino-functionalized hydrogel, enabling colorimetric detection of formaldehyde (FA). When the hydrogel reacts with FA, it undergoes volume shrinkage and a decrease in microsphere spacing, resulting in a blue shift in reflectance spectra and a color change from red to cyan. This photonic hydrogel shows high sensitivity, selectivity, and accuracy for detecting FA in air and aquatic products, providing a new approach for designing responsive photonic hydrogels for other target analytes.

Summary: Introduction of ABTS as an electron shuttle in the HRP/H2O2 system enhanced the degradation efficiency of diclofenac under neutral pH conditions. The green-colored ABTS radical was identified as the main reactive species in the HRP/H2O2/ABTS system, showing no destruction and serving as an ideal electron shuttle. The reaction conditions including solution pH, HRP concentration, and H2O2 concentration impacted the formation of ABTS radical and the degradation of diclofenac in the system.

Summary: In this study, optimal conditions for coating a rubidium vapor cell with octadecyltrichlorosilane (OTS) as an anti-relaxation coating were determined using an orthogonal experiment method. The results showed that OTS concentration, soaking time, and molar ratio/(H2O:OTS) significantly affected the number of bounces. The anti-relaxation performance was significantly improved by reducing the number and coverage ratio of clusters on the coating.

Summary: PCHs, consisting of PCs and stimuli-responsive hydrogels, act as a sensing system for specific analytes by undergoing volume phase transitions upon exposure to external stimuli. The VPT of the hydrogel causes changes in the photonic stopband of the PCs, leading to shifts in Bragg diffraction peak wavelengths. This sensing mechanism allows for the development of various PCH sensors capable of detecting external stimuli.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: This study presents a method to fabricate independently functioning microneedle (MN) electrodes with narrow intervals for high precision electrochemical sensing. The optimized mixture of photocurable polymer and single-wall carbon nanotubes was used to mold single composite MNs, which were then attached to pre-patterned electrodes. Plasma etching and electropolymerization were performed to enhance the electrochemical activity, and Prussian blue and glucose oxidase were electrodeposited on the MNs for glucose detection. The MN electrodes showed good sensitivity and linearity, and the feasibility of glucose detection was demonstrated in an in vivo mouse study.
