Special Issue Information

Dear Colleagues,

The ideal healthcare system should offer disease identification and treatment prior to the onset of the disease. The majority of medical diagnoses today depend on blood analysis in centralized laboratories that demand costly, labor-intensive clinical equipment and, more crucially, do not provide continuous monitoring capabilities. Patients who need quick medical diagnoses and care may be prevented from receiving these as a result. With the rapid advancements in nanotechnology, the topic of wearable bio/chemical sensors has recently attracted enormous attention worldwide because it can provide a unique solution to current medical problems by continuously monitoring physiological and/or biochemical markers, which is crucial for many chronic illnesses, neurological disorders, depression, and drug addiction. These wearable devices can be embedded in both textiles and the epidermis to evaluate sweat components in a non-invasive and unobtrusive manner. However, these devices have major hurdles in areas such as sweat collection, sensing array design, active materials, multiplexity, biocompatibility, air permeability, device stability, power consumption, real-time data transmission, and so on. By fulfilling all these tasks, it is expected that, in the near future, these wearable bioelectronics platforms will replace the traditional diagnostic medical devices, providing prompt response and warning in sufficient time for action, acceptable sensitivity and selectivity, and few false-positive and false negative results.

The modern healthcare system strives to provide patients with more comfortable and less invasive experiences, focusing on noninvasive and painless diagnostic and treatment methods. A key priority is the early diagnosis of life-threatening diseases, which can significantly improve patient outcomes by enabling treatment at earlier stages. While most patients must undergo diagnostic procedures before beginning treatment, many existing methods are invasive, time-consuming, and inconvenient. To address these challenges, electrochemical-based wearable and point-of-care (PoC) sensing devices have emerged, playing a crucial role in the noninvasive, continuous, periodic, and remote monitoring of key biomarkers. Due to their numerous advantages, several wearable and PoC devices have been developed. In this focused review, we explore the advancements in metal–organic frameworks (MOFs)-based wearable and PoC devices. MOFs are porous crystalline materials that are cost-effective, biocompatible, and can be synthesized sustainably on a large scale, making them promising candidates for sensor development. However, research on MOF-based wearable and PoC sensors remains limited, and no comprehensive review has yet to synthesize the existing knowledge in this area. This review aims to fill that gap by emphasizing the design of materials, fabrication methodologies, sensing mechanisms, device construction, and real-world applicability of these sensors. Additionally, we underscore the importance and potential of MOF-based wearable and PoC sensors for advancing healthcare technologies. In conclusion, this review sheds light on the current state of the art, the challenges faced, and the opportunities ahead in MOF-based wearable and PoC sensing technologies. Full article

Sweat, commonly referred to as the ultrafiltrate of blood plasma, is an essential physiological fluid in the human body. It contains a wide range of metabolites, electrolytes, and other biologically significant markers that are closely linked to human health. Compared to other bodily fluids, such as blood, sweat offers distinct advantages in terms of ease of collection and non-invasive detection. In recent years, considerable attention has been focused on wearable sweat sensors due to their potential for continuous monitoring of biomarkers. Electrochemical methods have been extensively used for in situ sweat biomarker analysis, as thoroughly reviewed by various researchers. This comprehensive review aims to provide an overview of recent advances in non-electrochemical methods for analyzing sweat, including colorimetric methods, fluorescence techniques, surface-enhanced Raman spectroscopy, and more. The review covers multiple aspects of non-electrochemical sweat analysis, encompassing sweat sampling methodologies, detection techniques, signal processing, and diverse applications. Furthermore, it highlights the current bottlenecks and challenges faced by non-electrochemical sensors, such as limitations and interference issues. Finally, the review concludes by offering insights into the prospects for non-electrochemical sensing technologies. By providing a valuable reference and inspiring researchers engaged in the field of sweat sensor development, this paper aspires to foster the creation of innovative and practical advancements in this domain.
