Nano-Based Electrochemical (Bio)sensors for Environmental Monitoring

Dear Colleagues,

Environmental pollution in most areas around the world needs to be controlled. Depending on the area and the ‘situation’, the environmental monitoring varies, and for this reason, it is necessary for different tools to be used. Electrochemical sensors are one of the tools that could contribute to air, water, soil, salinity and contamination monitoring. Accurate quantification of undesirable parameters that affect the quality of the environment is essential in order to protect it or to ameliorate it. Electrochemical sensors offer quick, simple, and accurate detection even at trace levels, also offering the possibility for in situ measurements at the pollutant source. The development of nanomaterials and other materials technologies have radically improved electrochemical sensors’ operational parameters, and so in recent years we have observed the application of low- and high-temperature electrochemical sensors for environmental parameter detection and monitoring. Despite the fact that there are many commercial sensors, there is still room for exploration. Many research groups have focused on lowering the limits of detection, while at the same time increasing the selectivity towards a specific contaminant/pollutant, of an electrochemical (bio)sensor.

This Special Issue welcomes new methodologies of the development of special electrochemical sensors or platforms that could probably contribute to environmental monitoring. Additionally, this Issue aims to highlight the potential future directions of this area and at the same time to give the opportunity to the readers to identify the research gaps.

Electrochemical sensors fit exactly with the aims of the ‘Sensors’. The as-suggested Special Issue proposal specializes the Issue to electrochemical sensors that are developed for environmental monitoring.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
