Special Issue Information
Dear Colleagues,
The trace analysis of toxic chemicals with current analytical methods is generally performed using bulky, sophisticated, and expensive lab-based techniques that often require cumbersome pre-concentration and separation methods, and can require expensive reagents, relying on highly trained technicians to perform the complex multi-step sample preparation and analytical procedures. Furthermore, these methods are impractical for large-scale real-time health and environmental monitoring.
Therefore, there is a critical need for a portable, mass-producible, and rapid sensor technology that is amenable to large scale, on-site detection of a diverse array of toxic and other contaminants (e.g., neurotoxins, heavy metals, pesticides, and biochemical markers) with sufficiently accurate sensor metrics (i.e., sensitivity, selectivity, limit of detection, and linear range). Electrochemical techniques with highly multiplexed electrode arrays and miniature potentiostats offer a viable economical means of detecting different classes of chemicals via direct oxidation or reduction at a modified working electrode. However, challenges remain in designing an affordable eco-friendly electrochemical sensor that can operate reliably in minimally or unprepared real-world samples.
We welcome your contribution to this Special Issue, where we aim to publish state-of-the art research results of electrochemical sensors that focus on innovative electrode and sensor designs, novel transduction mechanisms, new materials, coatings, and processes that could be transformative for monitoring and ameliorating public health and environmental concerns.

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. Micromachines 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 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.
