Single to use sensors that eliminate the electrode maintenance. Specially designed to work with microvolumes, this inexpensive miniaturized solution presents high reproducibility making them ideal for working in decentralized assays or to develop (bio)sensors in environmental, clinical or agri-food areas. The different modifications applied to the working electrode provide an enhanced active area and improve the electron-transfer properties.
Environmental friendly determination of heavy metals at ppb levels, avoiding mercury based electrodes. Also,this electrochemical platform is useful for developing other (bio)sensing applications in multiple sectors and fields.
For best results in the detection of heavy metals, electrochemical reduction of bismuth oxide to bismuth is recommended prior startign to measure.
The pretreatment conditions are described below:
Supporting electrolyte: KOH 0.1 M
Reduction time: 600 s
Reduction potential: -1.2 V
