Special Issue Information

Dear Colleagues,

Nanosensors integrate sensor recognition elements with advanced nanomaterials, making them powerful tools in bioanalysis. By utilizing the unique properties of nanomaterials, nanosensors enable the precise detection of biological targets. As the demand for more efficient, rapid, accurate, and sensitive analytical techniques grows, the role of nanosensors in bioanalysis continues to expand, driving significant advancements in both research and clinical practices.

We are pleased to invite you to contribute to our Special Issue, "Nanosensors for Bioanalysis". This Special Issue aims to present and highlight a collection of high-quality articles that explore the novel methodologies, developments, and applications of nanosensors in bioanalytical chemistry. Original research articles and reviews are both welcome in this Special Issue. Potential research areas may include (but are not limited to) the following:

  • Development of novel nanosensors for drug, metabolite, protein, nucleic acid, and other biomolecule detection in various biological matrices;
  • Emerging nanomaterial preparation, characterization, and applications in bioanalysis;
  • Applications of nanosensors in clinical diagnostics, disease biomarker detection, and Point-of-Care testing (POCT);
  • Integration of microchips/microfluidics and nanosensors for advanced bioanalysis;
  • Innovations in DNA/RNA nanotechnologies for sensing detection;
  • Advances, challenges, and future trends in nanosensors for bioanalysis.

I look forward to receiving your valuable contributions to this Special Issue and advancing bioanalytical nanosensor research together.

Background/Objectives: In this study, AuDNs/EPLE composite electrodes with hierarchical dendritic nanogold structures were fabricated using the in situ electrodeposition of gold nanoparticles through the i-t method. Methods: A conductive polymer composite membrane, PEDOT, was synthesized via the electropolymerization of EDOT and the negatively charged PSS−. The negatively charged SO3− groups on the surface of the PEDOT membrane were electrostatically adsorbed with the glucose oxidase (GOD) enzyme and a positively charged chitosan co-solution (GOD/chit+). Using a layer-by-layer self-assembly approach, GOD was incorporated into the multilayers of the composite electrode to create the composite GOD/chit+/PEDOT/AuDNs/EPLE. Results: Electrochemical analysis revealed a GOD surface coverage of 8.5 × 10−10 mol cm−2 and an electron transfer rate of 1.394 ± 0.02 s−1. The composite electrode exhibited a linear response to glucose in the concentration range of 6.923 × 10−2 mM to 1.54 mM, with an apparent Michaelis constant of 0.352 ± 0.02 mM. Furthermore, the GOD/chit+/PEDOT/AuDNs/EPLE also showed good accuracy of glucose determination in human serum samples. Conclusions: These findings highlight the potential of the GOD/chit+/PEDOT/AuDNs/EPLE composite electrode in the development of efficient enzymatic biofuel cells for glucose sensing and energy harvesting applications.

Viral infectious diseases pose a serious threat to global public health due to their high transmissibility, rapid mutation rates, and limited treatment options. Recent outbreaks of diseases such as plague, monkeypox, avian influenza, and coronavirus disease 2019 (COVID-19) have underscored the urgent need for efficient diagnostic and surveillance technologies. Focusing on viral infectious diseases that seriously threaten human health, this review summarizes and analyzes detection techniques from the perspective of combining viral surveillance and prevention advice, and discusses applications in improving diagnostic sensitivity and specificity. One of the major innovations of this review is the systematic integration of advanced biorecognition and detection technologies, such as bionanosensors, rapid detection test strips, and microfluidic platforms, along with the exploration of artificial intelligence in virus detection. These technologies address the limitations of traditional methods and enable the real-time monitoring and early warning of viral outbreaks. By analyzing the application of these technologies in the detection of pathogens, new insights are provided for the development of next-generation diagnostic tools to address emerging and re-emerging viral threats. In addition, we analyze the current progress of developed vaccines, combining virus surveillance with vaccine research to provide new ideas for future viral disease prevention and control and vaccine development, and call for global attention and the development of new disease prevention and detection technologies.
