Summary: Flexible electronics have great potential for applications beyond standard electronics, and recent technological advances have expanded their range of uses. This study introduces a novel method for creating flexible conductive carbon nanotube (CNT) films on different substrates. The resulting films showed satisfactory conductivity, flexibility, and durability, maintaining their conductivity even after bending cycles. The fabrication process is dry, solution-free, and suitable for mass production. The films exhibited uniform dispersion of CNTs on the substrate, and were successfully applied for collecting electrocardiogram (ECG) signals with better performance than traditional electrodes. The demonstrated fabrication process of flexible conductive CNT films holds significant promise for the field of bioelectronics.

Summary: Our previous study found that fumigation treatment using 1-octen-3-ol effectively induced resistance to peach fruit diseases. However, 1-octen-3-ol is not ideal for storage and application as it is a liquid fumigant. Therefore, we developed a novel material, 1% agar gel compound with 1% curdlan, to cover 1-octen-3-ol. The new compound hydrogel effectively retained and released 1-octen-3-ol, inducing resistance to peach fruit diseases.

Summary: In this study, the genes involved in the biosynthesis of 1-octen-3-ol in Agaricus bisporus, including AbLOX, AbLDS1, AbLDS2, and AbHPL, were identified and cloned. AbLOX and AbHPL were found to catalyze the conversion of linoleic acid to 1-octen-3-ol. Reduced AbLOX expression was correlated with a decrease in 1-octen-3-ol yield in antisense AbLOX transformants.

Summary: This study investigated whether the volatile organic compound 1-octen-3-ol is involved in the mechanisms of ectomycorrhizal (ECM) fungi that modulate below and aboveground communities. Through three in vitro assays, it was found that 1-octen-3-ol had dose-dependent effects on mycelium growth of three ECM species, inhibited seed germination, and influenced host plant traits. These findings suggest that 1-octen-3-ol may mediate changes in below and aboveground communities by regulating the release of ECM fungal volatiles.

Summary: This paper presents a modification to carbon nanotubes (CNTs) to improve the sensitivity to volatile organic compounds (VOCs) and enhance the stability of CNT sensors. By growing titanium dioxide nanowires (TiO2-NW) on the surface of CNTs, the sensors show increased sensitivity and reduced response time. Using virtual arrays of an electronic nose (E-nose), new features are extracted from the data and classified using support vector machine (SVM) algorithms. The paper achieves high accuracy in classifying different VOC gases.

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.
