Dual‐Hydrogen Bond Donor‐Functionalized Carbon Nanotube Fibers: Enhancing Anion‐Sensing Performance Through Functionalization Approaches (Small 6/2025)

Anion Sensors In article number 2405070, Hyeon Su Jeong, Seon-Jin Choi, and co-workers elucidated the effective electrical transduction property of chemiresistive anion sensors by comparing the functionalization techniques of selectors onto the carbon nanotube fiber. Various dual-hydrogen bond donor-based selectors were developed and functionalized either by covalently or non-covalently. Much improved acetate sensing performance was achieved by non-covalent functionalization with the demonstration of real-time wireless detection of acetate using a smartphone.
