Special Issue Information

Dear Colleagues,

Electrochemical sensors have attracted considerable attention for the sensitive detection of a variety of chemical, biological, and pharmaceutical compounds in water and the environment with simplicity and higher precision. Carbon-based nanomaterials, including but not limited to carbon nanotubes, C60, and graphene, have shown tremendous benefits in these types of electrochemical sensors due to their exceptional thermal, mechanical, electronic, and electrocatalytic properties. 

This Special Issue will focus on state-of-the-art developments and advances in sensing mechanisms, fabrication techniques, materials, and methodologies for the development of carbon-nanomaterial-based electrochemical sensors for water and environmental applications. The potential topics, for which we invite contributions, include but are not limited to the following, related to water and environment monitoring and sensing:

  • Carbon-nanomaterial-based electrochemical and bioelectrochemical sensors;
  • Functional carbon nanomaterials for sensing applications;
  • Active and passive sensors based on carbon nanomaterials;
  • Flexible and printed electrochemical sensors and electronics;
  • Green and environmentally friendly fabrication of carbon nanomaterials for electrochemical sensing;
  • Theoretical modeling and optimization of carbon-nanomaterial-based electrochemical sensors.

Manuscript Submission Information

Manuscripts should be submitted online at 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.

We studied electrochemical sensors using printed carbon nanotubes (CNT) film on a polyethylene telephtalate (PET) substrate. The mechanical stability of the printed CNT film (PCF) was confirmed by using bending and Scotch tape tests. In order to determine the optimum sensor structure, a resistance-type PCF sensor (R-type PCF sensor) and a comb-type PCF sensor (C-type PCF sensor) were fabricated and compared using a diluted NH3 droplet with various concentrations. The magnitude of response, response time, sensitivity, linearity, and limit of detection (LOD) were compared, and it was concluded that C-type PCF sensor has superior performance. In addition, the feasibility of PCF electrochemical sensor was investigated using 12 kinds of hazardous and noxious substances (HNS). The detection mechanism and selectivity of the PCF sensor are discussed. Full article
