Special Issue Information
Dear Colleagues,
Antibody–antigen interactions are often employed in analytical methods with applications in various fields such as biomedicine, toxicology, food industry, and environment chemistry. Analytical throughput is greatly improved by automation, but even so some problems remain, such as the application of immunoassay in situ or the simultaneous search for more analytes in a sample. These problems are overcome or at least alleviated by combining immunoreactivity with suitable transducers to form an immunosensor that provides the required analytical information in real time. Transduction can be obtained either by labelled or unlabelled pathway using several instrumental methods, among which electrochemical methods represent the most suitable and developed.
The aim of this Special Issue is to focus on the most recent strategies and developments of electrochemical immunosensors that, overcoming the need of expensive and time-consuming laboratory tests and making the analytical results readily available, can allow the early diagnosis and point-of-care diagnostics. Papers should address the employment of potentiometric immunosensors based on either electric charge density change or formation of ion channels, amperometric immunosensors based on either enzyme labeling or the use of redox probes, electrochemical impedance and conductance based immunosensors; in addition, the use of nanomaterials and imprinting polymers to enhance sensitivity and selectivity and to provide a suitable platform for immunochemical recognition system immobilization, should be also considered.
Both review articles and original 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. 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.
