Construction of a Smart Nanofluidic Sensor through a Redox Reaction Strategy for High-Performance Carbon Monoxide Sensing

Abstract

Carbon monoxide (CO), an important gas signaling molecule, demonstrated various physiological and pathological functions by regulating the ion flux of biological channels. Herein, inspired by the CO-regulated K+ channel in vivo, we propose a smart CO-responsive nanosensor through the redox reaction strategy. Such nanosensor demonstrated an outstanding CO specificity and selectivity with high ion rectification (∼9) as well as excellent stability and recyclability. Therefore, these results will provide a new direction for the design of nanochannel-based sensors for future practical and biological applications.

Recent development of near-infrared photoacoustic probes based on small-molecule organic dye

“…Studies have shown that oxidative stress can induce intracellular redox imbalance and biomolecular damage, leading to the occurrence of many diseases, including cancer and cardiovascular disease. 93,94 Although ROS has damaging effects, it also has positive effects. For example, photodynamic and sonodynamic therapy based on an appropriate increase in the reactive oxygen species can induce cell senescence and apoptosis, thereby showing anti-tumor functions.…”

RNA-Seq Explores the Mechanism of Oxygen-Boosted Sonodynamic Therapy Based on All-in-One Nanobubbles to Enhance Ferroptosis for the Treatment of HCC

“… 25 These emerging non-invasive techniques have been widely used in antitumor research. 26 , 27 However, due to the intrinsic or obtained resistance of cancer cells on apoptosis, the effectiveness of SDT in tumor-induced induction is limited. Therefore, the other non-apoptotic cell death model has opened new treatment pathways for eliminating cancer cells and reducing the resistance brought about apoptosis.…”

Interconnected CeO2 Nanofibers for Enhanced CO Gas Sensing

“…According to the ordinances of the National Institute of Occupational Safety and Health, the lethiferous exposure concentration and endurance of CO gas is 35 ppm for endurance of 10 h and 50 ppm for endurance of 8 h [7]. Therefore, it is particularly important to monitor CO leakage in the synthesis and application of CO as fast as possible [8].…”
