Special Issue Information
Dear Colleagues,
The genial invention of polarography in 1922 by Czech electrochemist Jaroslav Heyrovský (Nobel prize in 1959) not only opened up various applications of electrochemical methods in analytical chemistry, but it also influenced all branches of chemistry. In the second half of the 20th century, it was observed that polarography is fully compatible with computers and information technologies, which allowed extremely fast data acquisition and current-potential dependence recording. This modification of polarography (voltammetry) is able to use stationary working electrodes from various solid materials, making it fully compatible also with nanotechnologies. These electrodes may be used as cheap, fast, and sensitive detectors, bringing information about content of certain analytes in samples from pharmacy, biology, and environment or from food and commercial product control. Voltammetric detection techniques have reasonably high selectivity, but in the case of complex samples, the selectivity and possibility to correctly determine the content of certain analytes could be a problem. However, in contemporary electroanalysis, many successful sensors and/or methodologies for highly sensitive and highly selective determination of important analytes in complex samples have been introduced using progressive electrode material and/or novel detection strategies.
I believe that those of you who contribute to this Special Issue will enhance the number of successful applications of voltammetric techniques in sensitive and highly selective determinations in complex samples.

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. Molecules 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 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.
