Electrochemical Bioassays for Cancer Diagnosis and Management

Dear Colleagues,

The increase in life expectancy along with poor habits have made cancer a highly prevalent disease worldwide, constituting a major challenge of modern medicine. Early cancer diagnosis, even before clinical symptoms, is the key to minimize cancer-related deaths and reduce the healthcare expenditure of cancer care. Likewise, prognosis, surveillance, and treatment response evaluation are of great importance. Liquid biopsy is a promising strategy to tackle these important challenges, but it is conditioned by the availability of biomarkers with the required sensitivity and clinical specificity, present in accessible biological fluids, whose search is a continually evolving and developing area. Electrochemical platforms/approaches in combination with traditional (antibodies and hybridization nucleic acid probes) or novel synthetic bioreceptors (PNAs, LNAs, aptamers, and affibodies, among others) are turning out to be well-suited in this emerging field.

The aim of this Special Issue is to highlight the latest advances in electrochemical sensing technologies with application in cancer diagnosis and management. Thus, approaches leading to boost both analytical sensitivity and selectivity (such as the employment of nanomaterials and nucleic acids modifying enzymes) are welcome. Authors are kindly invited to share their research innovations as well as reviews of the state of the art in this field.

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. Biosensors 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 2200 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.
