Special Issue Information
Dear Colleagues,
Rapid progress in the analysis of disease-related biomarkers has led to a steadily increasing demand and unmet need for high-performance sensor technologies. Implementation of aptamer technologies coupled with electrochemical, optical, or many other techniques may provide an effective means toward the goal of rapid, sensitive detection of clinically relevant biomarkers. Aptamers, also known as “artificial antibodies”, are short single-stranded DNA/RNA oligonucleotides, or peptides that can be selected from synthetic libraries using a convenient in vitro selection approach, for example, systematic evolution of ligands by exponential enrichment (SELEX). This convenient selection approach, in retrospect, enables aptamers to bind a wide variety of target analytes, including small molecules, proteins and even cells, etc. Correspondingly, aptamer-based sensor technology is modular in a “plug-and-play” fashion, meaning that a general platform can be fabricated for the analysis of a broad range of targets, simply by replacing one aptamer by another. Complementary strategies (such as enzyme or nanomaterial amplifications ) can be employed into such technology to rationally tune affinity (ranging from micro- to picomolar level) and specificity.
This Special Issue on this topic will summarize advances and cutting-edge research work on aptamer-based technology for the analysis of biomarkers. We warmly welcome and look forward to your submission.

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.
