A micro-interdigitated array electrode-based microfluidic chip for the online detection of Hg(II)
To meet the demand for rapid on-site detection of trace Hg2+ in aquatic environments, this paper presents an integrated microfluidic electrochemical sensor based on micro-electromechanical systems technology. The core component of the sensor is a Au-based micro-interdigitated array (MIDA) electrode, which utilizes the...
