Special Issue Information
Dear Colleagues,
Since the report by Bard in 2002, which described the behavior of silicon quantum dots in non-aqueous media, quantum dots (QDs) have gained significant attention for their potential in electrochemiluminescence (ECL) applications. These QDs possess controllable sizes and exceptional luminescence properties, which make them promising for ECL applications. QDs are increasingly being utilized with immune recognition for the sensitive detection of biomarkers. As a result, the application of QDs with ECL properties has become a valuable technique for the analysis of biological samples in various fields, including clinical diagnostics, environmental monitoring, and food safety assessment. Ongoing research in this area is expected to continue to refine and improve the effectiveness of this technique. At the same time, the demand for highly sensitive ECL bioassays is growing, and various sensing strategies for ECL analysis based on QDs have been developed. While QDs-based ECL biosensors are still in the research stage and are less likely to be commercially available, the study of high-sensitivity and selective detection is still the main direction of current research efforts. However, toxicity effects, biomass analysis, and detection efficiency, which are all key to advance QDs-based biosensors for ECL commercial applications, should also be considered. The development of QDs-based ECL biosensors presents a promising future for the detection of biomolecules, yet they still face significant challenges. Thus, improving the feasibility and reliability of QDs-based ECL biosensors is still a vital reseacrh goal.

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 2200 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.
