“…A portable multianalyte device, based on a different recognition strategy was designed by R. K. Mishra et al for Hg 2+ , Pb 2+ , and Cd 2+ [40], obtaining a LOD of 1, 0.7, and 0.02 μg/L respectively. The device exploits a luminol–H 2 O 2 mixture as a chemiluminescent system and horseradish peroxidase (HRP).…”

: Microsystems and biomolecules integration as well multiplexing determinations are key aspects of sensing devices in the field of heavy metal contamination monitoring. The present review collects the most relevant information about optical biosensors development in the last decade. Focus is put on analytical characteristics and applications that are dependent on: (i) Signal transduction method (luminescence, colorimetry, evanescent wave (EW), surface-enhanced Raman spectroscopy (SERS), Förster resonance energy transfer (FRET), surface plasmon resonance (SPR)); (ii) biorecognition molecules employed (proteins, nucleic acids, aptamers, and enzymes). The biosensing systems applied (or applicable) to water and milk samples will be considered for a comparative analysis, with an emphasis on water as the primary source of possible contamination along the food chain.
