Nanomaterial-Based Biosensors to Support the One Health Concept

Dear Colleagues,

Access to sufficient, safe and nutritious food is one of the basic human needs in order to maintain a healthy and active life. Over the past century, the quality of life has been considerably increased around the world. We are healthier, richer, safer, and live longer than ever before. However, there is a downside to this success. Recent food adulteration scandals have affected consumer trust, and clearly alert us of the risks associated with possible contaminations at any points in the food value chain. We have also witnessed a dramatic increase in foodborne and infectious diseases due to the fast-growing worldwide trade in livestock, food products in combination with the increase in human mobility. Due to their rapid proliferation, single viruses or bacteria can result in a pandemic and cause millions of deaths and enormous economic losses—the COVID-19 pandemic is a vivid example. Therefore, it is important to ask how we can effectively manage and control foodborne outbreaks at their first onset. How can we ensure that food products produced locally or imported are genuine, safe, and of acceptable quality to consumers? These questions are being asked by more people, more frequently, and are among the world’s remaining grand challenges.

With their extremely small size and unique optical, electrical, and catalytic properties, nanomaterials can offer opportunities to develop biosensor platforms which can provide the sensitive, low-cost, rapid, and on-site detection of not only animal and plant diseases but also environmental conditions, thus providing us with better approaches to control and prevent diseases, economic loss, and adverse impact to our health. This Special Issue of Biosensors will be devoted to bringing together review and original research articles discussing nanomaterials-based biosensors for the detection of not only food contaminants but also animal and plant diseases as well as environmental conditions that directly or indirectly impact human health through the food chain. We cordially invite scientists working in different disciplines to submit their work for this Special Issue. Potential topics include, but are not limited to, nanomaterials-based biosensors for:

• The detection and identification of biological and chemical contaminants in foods and feeds, and in the environment;
• Monitoring the health of farming animals;
• Monitoring the quality, integrity, and safety conditions of food during production, transportation, and storage.

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.
