“…Both prokaryotic and eukaryotic whole cell electrochemical biosensors have been developed for heavy metal ion detection. ,− The use of living cells as biological sensing elements allows flexibility in determining the sensing strategy, and they are a cheaper alternative to purified enzymes or antibodies . In addition, enzymes and other biomolecules in living cells are in their native environment and display optimal activity and specificity toward the analyte of interest.…”

The release of chemicals into water systems has resulted in pollution in many parts of the world, threatening human health and aquatic ecosystems. Sources of chemical discharge include industry, agricultural, wastewater treatment plants, and stormwater overflows. To combat water pollution, the European Union has introduced several directives that set concentration limits for chemicals in drinking water, surface water, and groundwater. To meet these limits, it is essential that rapid, reliable, and sensitive analytical detection systems be developed and put into use. This Review presents the progress made in the development of electrochemical biosensors for environmental toxicants (pesticides and heavy metals) over the past seven years (2014–2020). For those unfamiliar with this field of research, the concept of a biosensor is introduced followed by a critical evaluation of their performance in detecting the toxicants. Current challenges are discussed as well as potential avenues for future research, including the demands for enhanced analytical performance, improved biosensor stability and shelf life, and greater integration with microfluidic devices and wireless database technologies for remote environmental sensing applications. We believe that this Review will be beneficial and enhance awareness and appreciation of the role that electrochemical biosensors can play in protecting our environment and water resources.

“…The potential use of MFC technology as a sensor was demonstrated for the first time in 2003 by Kim et al 18 The authors showed that the organic content in the anolyte correlates with the output voltage generated by the MFC, with an outstanding stability in field for up to 5 years. 18 Subsequently, the use of MFC technology has been demonstrated for the monitoring of pH, 19 volatile fatty acids (VFAs), 20 pathogens, 21 copper, 22 chromium, iron and nitrate, 23 cadmium, 24 zinc 25 and pesticides. 26 …”

“…[17] Khan et al genetically engineered the non-electroactive strain E. coli with a flavin biosynthetic gene cluster transcriptionally controlled by the MerR family protein, ZntR, creating electroactivity dependent on zinc concentrations. [18] This allowed for E. coli to be used in a microbial fuel cell for detection of zinc in various environmental samples dependent on the voltage observed. The authors also investigated common heavy metal interferences to demonstrate the selectivity of their sensor, as shown in Figure 2, proving that the sensor is only producing a significant voltage increase in the presence of zinc and not other heavy metals.…”

Although the past 20 years have seen significant advances in tailoring materials for improving the performance of bioelectrochemical systems, recently, there have been efforts in utilizing the synthetic biology toolkit for engineering organisms for bioelectrochemical systems. This review discusses the use of synthetic biology to engineer non-native properties into bioelectrochemical systems for increasing the diversity of fuel utilization in energy applications, allowing for novel electrosynthetic strategies, and improving the selectivity of biosensors. The review also discusses synthetic biology strategies for improving the abiotic/biotic interface, which improves the performance of bioelectrochemical systems. Both strategies are required and need to be combined with materials innovation to produce commercially viable bioelectrochemical systems in the future.
