Low-Cost Chemosenors for Applications in Environment, Health, Food, and Industry Process Control

Dear Colleagues,

Low-cost sensing refers to the use of affordable sensors to detect and measure the presence of chemicals. These sensors can be used in a wide variety of applications, including environmental monitoring, healthcare, food quality and safety, and industrial process control. Low-cost sensing technologies include, but are not limited to, the following: gas sensors in applications such as air quality monitoring, leak detection in industrial settings, or breath analysis in medical diagnostics; pH sensors used from water quality testing to food and beverage production; biosensors that use enzymes or antibodies to detect specific chemical compounds in medical diagnostics; colorimetric sensors that respond to a specific chemical reaction for integrated test kits; electronic noses with an array of chemical sensors to mimic the function of the human nose, identifying complex smells and tastes for food quality control or disease diagnosis.

Low-cost sensing can democratize access to important data and enable more widespread monitoring of chemical substances. However, like other low-cost sensing technologies, they may have limitations in terms of their accuracy, sensitivity, and selectivity compared to more expensive, laboratory-grade instruments. To overcome such disadvantages, recent developments in low-cost sensing have been driven by advances in materials science, nanotechnology, and information technologies, with key trends such as nanomaterials, printed electronics, paper-based sensors, wearable devices, the Internet of Things (IoT), Artificial Intelligence (AI), and Machine Learning (ML) making sensing more accessible, affordable, and effective, opening up new possibilities for monitoring and managing chemical substances in commercial products, the environment, and our bodies.

This Special Issue will encompass original research and reviews to benefit interested readers with knowledge of the state-of-the-art in low-cost sensing.

You may choose our Joint Special Issue in 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 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. 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 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.
