Special Issue Information

Dear Colleague,

This Special Issue of Biosensors invites papers on novel approaches in biosensors and biosensing platforms that address unmet needs in the rapid detection and diagnosis of diseases and biomarkers, particularly those with global societal impacts on human health, animal health, animal production, plant protection, water quality, environmental sustainability, food safety, biosecurity, and antimicrobial stewardship. The COVID-19 pandemic has also highlighted the need for the rapid detection of biomarkers and indicators in asymptomatic cases. A major focus of this Issue is addressing the accessibility of these biosensing technologies in terms of affordability, simplicity, and resource-limited operability and how they could be incorporated in the arsenal of prevention strategies against future pandemics. Papers and abstracts presented at the “2023 GARD Forum: Bridging Technologies and Market Needs” are welcome to this Special Issue.

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).

One of the most prevalent causes of foodborne illnesses worldwide is staphylococcal food poisoning. This study aimed to provide a robust method to extract the bacteria Staphylococcus aureus from food samples using glycan-coated magnetic nanoparticles (MNPs). Then, a cost-effective multi-probe genomic biosensor was designed to detect the nuc gene of S. aureus rapidly in different food matrices. This biosensor utilized gold nanoparticles and two DNA oligonucleotide probes combined to produce a plasmonic/colorimetric response to inform users if the sample was positive for S. aureus. In addition, the specificity and sensitivity of the biosensor were determined. For the specificity trials, the S. aureus biosensor was compared with the extracted DNA of Escherichia coli, Salmonella enterica serovar Enteritidis (SE), and Bacillus cereus. The sensitivity tests showed that the biosensor could detect as low as 2.5 ng/µL of the target DNA with a linear range of up to 20 ng/µL of DNA. With further research, this simple and cost-effective biosensor can rapidly identify foodborne pathogens from large-volume samples. Full article
