Abstract:The air plasma-induced defects and O- groups are employed as anchoring sites for the directional electrochemical deposition of Ag nanoparticles (AgNPs) with even distribution and a narrow size range on carbon cloth (CC). The strategy of integrating the air plasma and AgNPs provides plentiful adsorption and catalytic sites, a large electroactive area, superhydrophilic interface, and a smooth charge and mass-transfer pathway. As a consequence, the fabricated self-supporting electrode of AgNPs@CC - P displays an excellent sensing performance toward rutin with a large linear concentration window (0.05 similar to 30 mu M), a small LOD (4.2 nM, S/N = 3) and LOQ (32 nM, S/N = 10), as well as good stability and reproducibility. The fabricated sensor is successfully applied to the practical detection of rutin in tablets and beverages with good accuracy. The self-supporting sensor also shows potential for fabricating flexible and soft sensing devices for real-time monitoring.
