Special Issue Information

Dear Colleagues,

Electrochemical sensors and biosensors are crucial tools in modern science, offering unparalleled sensitivity, selectivity, and versatility for a wide range of applications. This Special Issue, titled “Electrochemical Sensors and Biosensors: Recent Progress, Challenges, and Future Perspectives”, aims to highlight the latest developments in sensor design, fabrication, characterization, and application. Contributions will focus on novel materials, such as nanomaterials, polymers, and composites, as well as cutting-edge techniques for enhancing performance and functionality. Topics will also include challenges in scaling up production, ensuring long-term stability, and improving biocompatibility for healthcare, environmental, and industrial applications. We invite researchers to share innovative solutions, interdisciplinary approaches, and insights into the future directions of electrochemical sensing technologies. By bridging gaps between fundamental research and real-world applications, this Special Issue will provide a comprehensive overview of the field's progress and challenges.

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.

Numerous research projects on biosensors have been conducted, and a substantial number of academic studies and conference papers on biosensors are published annually. However, only a few biosensors have been commercialized. In this review, we took blood glucose meters as an example to review the development, characteristics, and challenges of biosensors in the literature. The four subsystems of the physical sensors are illustrated to emphasize the importance of standardization and traceability in the sensors. The development of physical sensors, chemical sensors, and biosensors is introduced. The importance of reference materials as a standard for evaluating sensor performance is emphasized. The basic technique and four types of chemical transducers are described, and we show that the biosensors’ response must be processed with these chemical sensors. The characteristics of the glucose meter are introduced to explain the success of this sensor, especially the sensing materials of glucosidases. Two types of highly developed and competitive biosensors, continuous glucose monitoring (CGM) and paper-based biosensors, are introduced, and the trends and future implications of both biosensors are illustrated. The challenges facing biosensor development are summarized into several key factors, and future research directions are discussed. A list of factors for the successful commercialization of biosensors is also proposed. Full article
