Special Issue Information

Dear Colleagues,

Antibiotics have revolutionized the treatment of infectious diseases, but their overuse and misuse have led to the spread of antimicrobial resistance (AMR). The AMR is defined by the World Health Organisation (WHO) as the “ability of a microorganism (like bacteria, viruses, and some parasites) to stop an antimicrobial (such as antibiotics, antivirals and antimalarials) from working against it”. AMR represents an emerging threat to public health worldwide, resistance to antibiotics being on the rise, with many bacteria species becoming resistant to multiple classes of antibiotics simultaneously. This poses a serious threat as treatment options for severe infections become more and more limited. In order to combat AMR, the WHO has endorsed a Global Action Plan recommending, among others, strict surveillance of antibiotic use and extensive research in the field in order to fully understand the AMR phenomena.

Antibiotics detection from biological, food, and environmental samples can allow the identification of the optimal antibacterial treatment, diminishing allergic reactions and impairing the spread of AMR. The early and rapid identification of bacteria in food, biological, microbiological, and environmental samples is very important in the prevention, diagnosis, and treatment of bacterial infections and in the fight against AMR. Due to their many advantages, sensors and biosensors play an important role in the detection of antibiotics and bacteria from various matrices.

This Special Issue will focus on the latest trends in the development of (bio)sensors for the detection of antibiotics and bacteria. We are interested in examples of (bio)sensors covering the following and related topics: novel optical, electrochemical, piezoelectric, magnetic, and acoustic sensors for antibiotics and bacteria detection; the identification and detection of new bacterial biomarkers; the development of sensors using novel recognition elements (molecularly imprinted polymers, aptamers, peptides, enzymes, nanozymes, etc.); new immobilization strategies of the bioelements and new sensor materials; “lab-on-a-chip” and artificial-intelligence-assisted sensors; whole bacteria and biomarker detection; real-sample analysis: food, biological, microbiological, and environmental samples.

Review and original research papers are welcome.

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.

Titanium-copper alloy films with stoichiometry given by Ti1xCux were produced by magnetron co-sputtering technique and analyzed in order to explore the suitability of the films to be applied as resistive temperature sensors with antimicrobial properties. For that, the copper (Cu) amount in the films was varied by applying different DC currents to the source during the deposition in order to change the Cu concentration. As a result, the samples showed excellent thermoresistivity linearity and stability for temperatures in the range between room temperature to 110 °C. The sample concentration of Ti0.70Cu0.30 has better characteristics to act as RTD, especially the αTCR of 1990 ×106°C1. The antimicrobial properties of the Ti1xCux films were analyzed by exposing the films to the bacterias S. aureus and E. coli, and comparing them with bare Ti and Cu films that underwent the same protocol. The Ti1xCux thin films showed bactericidal effects, by log10 reduction for both bacteria, irrespective of the Cu concentrations. As a test of concept, the selected sample was subjected to 160 h reacting to variations in ambient temperature, presenting results similar to a commercial temperature sensor. Therefore, these Ti1xCux thin films become excellent antimicrobial candidates to act as temperature sensors in advanced coating systems. Full article
