Carbon Nanotube-based Chemical and Biochemical Sensors

Dear Colleagues,

Since their discovery in 1991, carbon nanotubes (CNTs) have been extensively studied due their extraordinary chemical and physical properties. They are unique 1D π-electron wires that possess quantised electronic states. Another advantage is the extreme sensitivity of CNTs to surface modifications due to their graphene-like surface structure of atomic thickness. Since every carbon atom is exposed to the surrounding environment, excitons traveling through the CNT surface are affected by local changes in dielectric, polarity and other perturbation that alter CNTs electronic properties. Therefore, they are ideal materials for the development of chemical and biochemical nanosensors. Tremendous effort has been dedicated to the modification of CNT side wall, notably through covalent and non-covalent interactions and create novel nanohybrids to improve specific interactions with a target analyte. This Special issue aims to gather original and high-quality research results on “Carbon Nanotube‐based Chemical and Biochemical Sensors” technology. CNTs should be used as transducers (optical or electrical) or passive sensitive layer (incorporated on resonant device for example) and modified by any type of physical and/or chemical techniques. Target analytes include but are not limited to the following:

• Volatile organic compounds and gases
• Metallic and non-metallic ions
• DNA, small molecules, enzyme, proteins, viruses, etc …

Review and research articles are equally welcome. Thank you in advance for your contribution!

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. Sensors 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 2600 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.
