Ultrasensitive detection of mercury (II) ions using electrochemical surface plasmon resonance with magnetohydrodynamic convection

“…Conventional methods for detecting mercury (II) ions, such as molecular, atomic, or fluorescence spectrometry [7,8], chromatography [9], enzyme-based biosensors [10], fiber optic probes and optical sensors [11,12], pool optode [13], stripping electrochemistry [14][15][16], and stripping electrochemistry coupled with piezoelectric sensor technology [17], are not highly appropriate due to a large sample volume and a long process of sample pretreatment required [18,19] or poor reproducibility [20], among other drawbacks. Thus, it is important to explore alternative techniques that are more accurate and less bulky and time-consuming.…”
