Special Issue Information

Dear Colleagues,

Electrochemical sensors have become essential for detecting and analyzing environmental pollutants in real time. They are highly sensitive and selective and provide fast measurements, making them crucial for managing and assessing environmental quality. Electrochemical sensors are utilized in various applications, such as monitoring air and water quality, detecting greenhouse gases, monitoring soil quality, and identifying emerging contaminants. Their portability and integration capabilities facilitate remote and mobile monitoring, enabling data collection in challenging environments. This Special Issue aims to emphasize the significance of electrochemical sensors in environmental applications and present the latest advancements in this field.

This Special Issue welcomes contributions (papers, communications, and reviews) that address the following broad topics (but not limited to):

  • Development and optimization of electrochemical sensor platforms for environmental monitoring.
  • Design and fabrication of novel sensing materials and electrode architectures.
  • Integrating electrochemical sensors with emerging technologies, such as the Internet of Things (IoT), data analytics, and Artificial Intelligence, for intelligent environmental monitoring systems.
  • Electrochemical sensors for analyzing and monitoring water quality, including detecting heavy metals, organic contaminants, and nutrients.
  • Applications of electrochemical sensors for the real-time monitoring of greenhouse gases
  • Electrochemical sensor-based approaches for detecting and quantifying emerging contaminants, such as pharmaceuticals, personal care products, and microplastics.

Ecological surveys of living things based on DNAs from environmental samples are attractive. However, despite simplicity of water sampling from the target environment, it is still necessary to transport the samples to the laboratory for DNA analysis based on skillful next-generation sequencers. To perform DNA-oriented surveys based on a simple protocol without any special training, we demonstrated, in this study, the detection of genes from cell-containing environmental waters using gene sensor arrays that require no DNA labeling and no external indicators. Cell-suspended PBS or river water were used as models of environmental waters containing living things, and DNA samples were prepared by PCR amplification. Ferrocene-terminated probes were synthesized and immobilized on an electrode array to develop a sensor array. The sensor array showed a large response to a target DNA complementary to the probe and no response to a mismatched DNA, indicating sequence-specific detection. For DNA samples prepared from the cells in PBS, they showed good responses similar to those for the target DNA. They also significantly detected DNA samples from the cells in river water at a general environmental concentration (38 cells mL−1) with 28-fold larger responses than those for 0 cells mL−1.
