Special Issue Information
Dear Colleagues,
Nanocarbon materials with different dimensions, including fullerenes, carbon dots, carbon nanotubes, graphene and graphene oxides, nanodiamonds, etc., have attracted enormous research interest due to their unique structural, physical, chemical, and electronic properties. Nanocarbon is one of the most intensively studied nanomaterials and has been widely used in many different fields, including energy conversion and storage, environment protection, catalysis, chemical and biochemical sensors, and biomedicine.
Biosensors are analytical devices that detect the presence of an analyte of interest, such as a biologically important small molecule (e.g., glucose and adenosine triphosphate), a biomolecule (e.g., peptides, DNAs, and enzymes), or a microorganism (e.g., viruses, bacteria, and cancer cells). Biosensors consist of three elements: a sensitive biological element that recognizes a specific analyte and produces a signal, a signal transduction element that transforms one signal into another, and a reading device that measures the signal. Various biosensors have been developed based on enzymes, tissues, antibodies, DNAs, etc. and widely used in the field of food safety, environmental research and protection, security and defense, biomedical research, and life sciences. They provide better stability, sensitivity, and feasibility compared to traditional methods.
Applications of nanocarbon materials in biosensors provide opportunities for developing a new generation of biosensors with improved mechanical, electrochemical, or optical properties, and overall performance of the biosensors. Nanocarbon-based biosensors can be classified into the following four categories according their transduction mechanism: (1) electronic biosensors using nanocarbon or hybrid nanocarbon-based composites as field-effect transistors; (2) electrochemical biosensors employing nanocarbon-modified electrodes; (3) optical and visual biosensors based on colorimetric detection, fluorescence quenching, Forster resonance energy transfer (FRET), and chemiluminescence; and (4) plasmonic biosensors using nanocarbon as a plasmonic layer or a sensitivity-enhancement material.
This Special Issue is dedicated to cutting-edge research and development based on nanocarbon materials that advance the field of biosensors. Original research articles, short communications, and reviews are all 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. 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 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.
