Deadline for manuscript submissions: 15 July 2019

Heavy metal ions coming from both natural and anthropogenic sources dramatically contribute to environmental pollution and constitute a serious threat for human health, especially considering its non-biodegradable character and the tendency to bioaccumulate and biomagnificate. This is why many international regulations stablish maximum concentrations for a series of metals and metalloids in water, food products and drugs, mostly based on toxicological studies. This requires the development of reliable analytical methods for the determination of such substances. For this purpose, inductively coupled plasma (ICP) techniques are very well suited, since they provide multi-element analysis with an excellent accuracy. However, ICP methods suffer from too high costs and lack of portability, which is a serious drawback in situations that require in situ measurements, fast and cheap screening of as much elements as possible or real-time monitoring in flow systems. In these cases, electrochemical, optical and hybrid sensors, alone or integrated into sensor arrays, can be a valuable alternative to ICP methods.
With these facts in mind, many efforts have been made in the last years to develop suitable sensors for the fast, low-cost, in situ, on-line detection of heavy metal ions. In this context, there is an increasing popularity of screen-printed devices, nanoparticles and nanomaterials and a growing interest on the combination of sensors into complex arrays and on the powerful chemometric methods required for processing the resulting multivariate data sets.
In this regards, this Special Issue aims to cover the advances in electrochemical, optical and hybrid sensing technologies for fast, reliable and affordable detection of heavy metal ions. Both research papers and review articles will be considered. We look forward to and welcome your participation in this Special Issue.
Potential topics may be the following:
- Electrochemical sensors for heavy metal detection based on screen-printed devices
- Electrochemical sensors for heavy metal detection based on nanoparticles and nanomaterials
- Modification of electrodes using different strategies (drop casting, electroplating, electrografting, electropolymerization, etc.) in order to detect heavy metals.
- Optical sensors for heavy metal detection
- Biosensors for the detection of heavy metals
- Heavy metal sensing in flow systems
- Electronic tongues and other sensor arrays for detecting heavy metals
- Chemometric methods for the analysis of data obtained with heavy metal sensors
- Application of heavy metal sensing to environmental analysis
- Heavy metal sensing in food science

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 papers will be 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.
