박경순 One-step process for ultrasensitive detection of mercuric ions using nanoparticle formation and single-entity electrochemistry Sensors and Actuators B: Chemical 8.0 0925-4005 431 SCIE Mercuric ions (Hg 2+ ) are common heavy-metal ions that pose a significant threat to human health due to their high toxicity. The detection of excessive concentrations of Hg 2+ is critical and requires highly sensitive electrochemical techniques. A novel electrochemical sensing technique was employed for the detection of Hg 2+ . This study emphasizes the use of single-entity electrochemistry (SEE) for the one-step synthesis and selective detection of nanoparticles in aqueous solutions. Importantly, this method does not require a catalyst or reducing agent for nanoparticle synthesis. The developed approach provides significant advantages over conventional techniques, such as increased sensitivity, improved selectivity, and the ability to detect low concentrations of 1 pM Hg 2+ without modifying the electrode surface and the linear range for Hg 2+ was obtained at 1 pM – 10 nM. This one-step synthesis and detection method is a reliable and promising tool for sensing trace heavy metals and studying the redox behavior of mercuric ions.
