Recent Achievements on Electrochemical Biosensors

Dear Colleagues,

The need for selective detection and determination of low concentrations of certain analytes in the shortest possible time of analysis has prompted continuous efforts aimed at the design and construction of new microanalytical devices. Of particular interest in this area are chemical sensors due to the possibilities they offer now and may offer in the future. Chemical sensors, along with their specific type with biological-origin components in the analyte identifying layer, i.e., so-called biosensors, are small mobile devices of simple construction and low price per unit. In this context, electrochemical detection techniques seem the most appropriate to use. This is because it is possible to analyze even the slightest changes noted in the receptor layer during analyte binding, which may in turn result in low detection limits or fast response times. Together with high selectivity secured by the biological receptor layer, these attributes make these devices particularly attractive for modern analytical methods dedicated to analyses of food products, clinically and environmentally important analytes, or the fast testing of toxic samples. Thanks to progress in the development of automation, electronics, material engineering or biomedical engineering, small and mobile analytical platforms have been constructed where (bio)sensors, especially electrochemical ones, are preferably used as detectors. Therefore, this Special Issue seeks to showcase research papers and review articles that focus on recent advances in electrochemical biosensors. 

I look forward to receiving your submissions.

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 250 words) can be sent to the Editorial Office for assessment.

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.
