Advances and Applications of Electrochemical Immunosensors

Dear colleagues,

The combination of specific antibody–antigen recognition with the high sensitivity and selectivity of electrochemical immunosensors has been the focus of tremendous interest and there has been significant progress over the past decade in early disease diagnostics in clinical applications, environmental monitoring, and food industry applications. Electrochemical immunosensors have many advantages, such as high sensitivity, operational simplicity, low instrumentational cost, the possibility for miniaturization, and the ability to detect trace amounts of analytical targets of biological significance on a scale ranging from nano to macro level and are also promising for point-of-care-testing. Electrochemical transducing methods such as voltammetric, potentiometric, conductometric, or impedimetric have been utilized in different applications because of their excellent properties, such as low-cost, sensitivity, and simplicity. A vast majority of recent research on electrochemical immunosensors has focused on various detection methodologies and incorporation of nanomaterials in design to achieve high sensitivity in terms of electrochemical change of signal transduction. This book focuses on recent developments of electrochemical immunosensors, with an emphasis on conventional methodologies of voltammetry, amperometry, electrochemical impedance, and innovative designs for transducer surface modifications and analytical platforms.

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 2100 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.
