Special Issue Information

Dear Colleagues,

Following the success of the first volume of the Special Issue entitled "Conjugated Polymers-Based Biosensors for Virus Detection", we are pleased to announce a new edition, entitled "Polymers-Based Biosensors and Bioelectronics: Designs and Applications". This Special Issue will continue to explore the innovative use of polymer materials in the development of biosensors and bioelectronic devices.

As the need for sensitive and selective detection methods grows in fields such as healthcare, environmental monitoring, and food safety, polymers have become indispensable materials. Their unique properties—such as flexibility, biocompatibility, and ease of functionalization—make them highly suitable for these applications.

This Special Issue will focus on recent advancements in the design, fabrication, and application of polymer-based biosensors and bioelectronic systems. We welcome the submission of original research articles, reviews, and short communications addressing a range of topics, including novel polymeric materials, integration techniques, sensing mechanisms, and practical applications in diagnostics and monitoring.

By gathering diverse contributions from researchers and industry experts, we aim to foster collaboration and knowledge exchange in this rapidly evolving field. We believe that this Special Issue will be a valuable resource for scientists and engineers working at the intersection of polymer science, biosensing technology, and bioelectronics, ultimately contributing to the advancement of next-generation sensing solutions.

Sweat is considered the most promising candidate to replace conventional blood samples for noninvasive sensing. There are many tools and optical and electrochemical methods that can be used for detecting sweat biomarkers. Electrochemical methods are known for their simplicity and cost-effectiveness. However, they need to be optimized in terms of selectivity and catalytic activity. Therefore, electrode modifiers such as nanostructures and metal–organic frameworks (MOFs) or combinations of them were examined for boosting the performance of the electrochemical sensors. The MOF structures can be prepared by hydrothermal/solvothermal, sonochemical, microwave synthesis, mechanochemical, and electrochemical methods. Additionally, MOF nanostructures can be prepared by controlling the synthesis conditions or mixing bulk MOFs with nanoparticles (NPs). In this review, we spotlight the previously examined MOF-based nanostructures as well as promising ones for the electrochemical determination of sweat biomarkers. The presence of NPs strongly improves the electrical conductivity of MOF structures, which are known for their poor conductivity. Specifically, Cu-MOF and Co-MOF nanostructures were used for detecting sweat biomarkers with the lowest detection limits. Different electrochemical methods, such as amperometric, voltammetric, and photoelectrochemical, were used for monitoring the signal of sweat biomarkers. Overall, these materials are brilliant electrode modifiers for the determination of sweat biomarkers. Full article
