Special Issue Information

Dear Colleagues,

(Bio)electrochemical sensors demonstrate promising applications in many emerging fields, such as food safety detection, environmental pollutant monitoring, and personalized healthcare. Among them, (bio)electrochemical sensors based on modified multifunctional nanomaterials are favored for their unique properties; for example, high electrocatalytic activity, large surface area and excellent biocompatibility. Nanomaterials (carbon nanotubes, graphene, carbon dots, black phosphorus, MXene, etc.) serve a critical role in the fabrication of novel (bio)electrochemical sensors to address the increasingly complex requirements for environmental monitoring, food safety, health monitoring, point-of-care diagnostics, and wearable devices. Notably, advanced sensors developed based on nanomaterials and nanotechnology combined with flexible wearable devices exhibit tremendous application potential, enabling the application of portable and intelligent wearable devices to human life.

This Special Issue is devoted to advanced (bio)electrochemical sensors based on the integration of multifunctional nanomaterials and will feature a comprehensive selection of recent research work, short communications, and review articles focusing on nanomaterials, design, fabrication methods, and multi-scenario applications of nanomaterial-based constructed electrochemical sensors. All manuscripts considered for publication in this section will undergo a rigorous peer review process, and decisions will be made based on the recommendations of independent reviewers.

Potential topics include, but are not limited to:

  • Electrochemical (bio)sensors;
  • Synthesis methods and structures of novel functional nanomaterials;
  • 0D nanomaterials (nanoparticles);
  • 1D nanomaterials (nanotube, nanofibers, nanowires);
  • 2D nanomaterials (graphene, other 2D layered nanomaterials);
  • Design and integration of multifunctional sensors;
  • Sensor multi-scene applications: food safety, environmental pollution and health management;
  • Construction and application of flexible wearable sensors.

Skin interstitial fluid (ISF) has emerged as a fungible biofluid sample for blood serum and plasma for disease diagnosis and therapy. The sampling of skin ISF is highly desirable considering its easy accessibility, no damage to blood vessels, and reduced risk of infection. Particularly, skin ISF can be sampled using microneedle (MN)-based platforms in the skin tissues, which exhibit multiple advantages including minimal invasion of the skin tissues, less pain, ease of carrying, capacity for continuous monitoring, etc. In this review, we focus on the current development of microneedle-integrated transdermal sensors for collecting ISF and detecting specific disease biomarkers. Firstly, we discussed and classified microneedles according to their structural design, including solid MNs, hollow MNs, porous MNs, and coated MNs. Subsequently, we elaborate on the construction of MN-integrated sensors for metabolic analysis with highlights on the electrochemical, fluorescent, chemical chromogenic, immunodiagnostic, and molecular diagnostic MN-integrated sensors. Finally, we discuss the current challenges and future direction for developing MN-based platforms for ISF extraction and sensing applications. Full article
