Nanomaterial-Based Electrochemosensors for Environmental Monitoring

Dear Colleagues,

Environmental emerging contaminants (EECs) can be synthetic or natural chemical products (including any microorganism) that, when present in the environment, can be the cause of known or suspected ecological adverse effects. Since these pollutants are not often detected, neither quantified nor monitored regarding time, the effects on ecosystems, including human health, are discovered when the magnitude of the damage becomes very difficult to abate.

Among others, EECs include pharmaceuticals, pesticides, industrial-grade chemicals, surfactants, and personal care products, as well as endocrine-disrupting compounds, analgesics, antibiotics, hormones, and a whole range of other pharmaceutical compounds, including anti-inflammatory, antidiabetic, and antiepileptic drugs. In all cases, these products are constantly discharged to groundwater, surface water, municipal wastewater, drinking water, and food sources.

In this way, electrochemosensors have been shown to be very sensitive technologies for monitoring known environmental pollutants in water, soil, and air. However, the detection and quantification of EECs by means of these technologies involve the increment of the electroactive area and the enhancement of the analytical selectivity. These qualities are often presented by nanomaterials having, for instance, a wide variety of optoelectronic, magnetic, or biomimetic properties. Therefore, it is reasonable to propose that the design and construction of nanomaterial-based electrochemosensors are growing as promising technological pathways for attending to the monitoring EECs entering the environment.

This Special Issue aims to provide some insights into recent development in electrochemosensors for the environmental monitoring of known and emerging environmental contaminants.

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.
