Printed Chemical Sensors

Dear Colleagues,

Chemical sensors are already mass-produced and are indispensable devices, for instance, in the environmental, agricultural, and medical fields, where molecules of great relevance like carbon monoxide, ammonia, and glucose are rapidly detected and quantified in situ. Obviously, this widespread use of sensors is of great interest in many other areas in which fast and reliable real-time monitoring is key, such as food and water safety, air pollution control or point-of-care diagnosis. For these applications (and many others), there are already a myriad of highly functional materials and sensing technologies described in the scientific and patent literature. However, they typically rely on fabrication methods that are not scalable and hence have low commercialization potential.

Advanced manufacturing methods have been receiving great attention in recent years due to the fact that they employ mainly low-temperature, low-pressure conditions and green chemicals for the fabrication of chemical sensors through solution-processing. More specifically, printing techniques are attractive since they are compatible with large-scale manufacturing and have been in use in industry for hundreds of years. Most printing techniques use environmentally friendly inks and simple instrumentation and are compatible with plastic substrates, thus enabling the fabrication of flexible devices. Perhaps the best example of the use of printing for the fabrication of commercial (bio)sensors is the glucose strip, the most successful biosensor in the market, which is in part manufactured by screen-printing.

In this Special Issue, we will publish a collection of manuscripts that describe the latest advances on the use of printing to fabricate chemical sensors. New materials and technologies will be reported, and focus will be given to the scalable aspect of sensor manufacturing. Topics of interest include but are not limited to:

• Functional (bio)inks
• Printed active layers and recognition elements
• Inkjet-printed components and devices
• High-throughput printed films for chemical sensing
• Screen-printing, gravure-printing, flexography, and slot-die coating for chemical sensors manufacturing
• Roll-to-roll (R2R) printed sensors
• Flexible chemical sensors
• Paper-based printed sensors
• 3D-printed and microfluidic-based chemical sensors

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. Chemosensors 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 2000 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.
