Toxic substances such as heavy metals, toxins, new xenobiotic compounds including pharmaceuticals, endocrine disruptors, surfactants, and industrial additives from industrial effluents, as well as other pollutants may contaminate aquatic resources and the drinking water system, thus menacing humans, agriculture, livestock, and wildlife. Regulatory authorities worldwide have set standards for these contaminants, where the permissible limits correspond to very low concentrations (i.e., pg/L or ng/kg). Considering the toxicity and ubiquity of these compounds, there is an immense need for the development of fast, sensitive, and reliable detection methods.

The current situation has driven the development of biosensors as new analytical tools able to provide fast, reliable, and sensitive measurements with low cost—many of them geared towards on-site analysis. Biosensors may not completely replace the official analytical methods, but can be used both by regulatory authorities and industry to simplify the routine testing and screening of samples.

Despite an incredibly high number of publications on biosensors in different fields (including environmental monitoring), the glucose sensor still represents more than 90% of the biosensors market. The time has come to profit from the wealth of accumulated knowledge and turn it into robust devices of advanced technology readiness level (TRL) for real applications in environmental monitoring.

The aims of this Issue “Biosensors for Environmental Monitoring” is to highlight recent methodological advances of level TRL1 or 2 in the field and to promote papers which describe systems working with real samples and validated in laboratory conditions, corresponding to TRL 3 and 4. Authors are invited to submit works exploring biosensors based on electrochemical, optical, or other detection modes, lab-on-a chip devices, advanced and automated sensing platforms, bioassays, and detection systems where nanomaterials play a critical, demonstrated role.

Both review articles and research papers are welcome.

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. Chemosensors is an international peer-reviewed open access monthly 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 2700 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.
