Special Issue Information

Dear Colleagues,

With the applications of nanomaterials in different dimensions, such as nanoparticles, nanowires, and nanosheets, flexible sensors have experienced vigorous development, reshaping people's understanding of the form and function of electronic sensors and systems. These sensors leverage the high specific surface area, high sensitivity, and tunable electronic properties of nanomaterials to achieve the highly sensitive and selective detection of various physical (e.g., pressure, temperature, humidity) and chemical (e.g., gases, pH) stimuli. Research on nanomaterial-based flexible sensors can be applied in the real-time monitoring of physiological signals in health monitoring, such as heart rate and blood oxygen saturation, playing a significant role in remote medical care and personal health management. Their applications in wearable devices like smartwatches and health trackers are becoming increasingly widespread, offering users more convenient and personalized services. They can also be used to detect harmful substances in the environment, like heavy metal ions and organic pollutants, providing technological support for environmental protection and public safety. In industrial automation, flexible sensors can be integrated into robots and automation equipment to enhance production efficiency and safety. The research on nanomaterial-based flexible sensors not only has a solid scientific foundation but also holds immeasurable value in driving technological innovation, improving quality of life, and safeguarding the environment. With further research and technological advancements, this field is poised to demonstrate broader application prospects in the future.

This Special Issue will present comprehensive research outlining progress on the application of nanomaterials or micro/nanostructures to improve the performance of flexible sensors. This includes the utilization of nanomaterials or micro/nanostructures to improve the performance of sensors, the construction of new flexible sensing interfaces and sensor structures, and the diversified applications of flexible sensors. We invite authors to contribute original research articles and review articles covering the current progress in flexible sensors based on nanomaterials. Potential topics include, but are not limited to, the following:

  1. Nanomaterial-based sensing mechanism;
  2. Wearable nano friction devices;
  3. Nanomaterial chemical sensors;
  4. Nanofiber-based sensing films;
  5. Tactile devices and integrated systems;
  6. Nano self-powered sensors;
  7. Flexible nanomaterials with multimodal features;
  8. Micro/nano bionics and structures for interface devices;
  9. Triggering interaction in metaverse/VR worlds with flexible sensors.

We look forward to receiving your contributions.

The increasing prevalence of toxic compounds in food, agriculture, and the environment presents a critical challenge to public health and ecological sustainability. Carbon nanodots (CNDs), with their excellent photoluminescence, biocompatibility, and ease of functionalization, have emerged as highly promising materials for developing advanced sensors that target hazardous substances. This review provides a comprehensive overview of the synthesis, functionalization, and sensing mechanisms of CND-based sensors, highlighting their versatile application in detecting toxic compounds such as heavy metals, pesticides, mycotoxins, and emerging contaminants. The article outlines recent advancements in fluorescence, electrochemical, and colorimetric detection strategies and presents key case studies that illustrate the successful application of CNDs in real-world monitoring scenarios. Furthermore, it addresses the challenges associated with reproducibility, scalability, selectivity, and sensor stability and explores future directions for integrating CNDs with smart and sustainable technologies. This review emphasizes the transformative potential of CNDs in achieving rapid, cost-effective, and environmentally friendly toxin detection solutions across multiple domains. Full article
