“…The electrochemical-based bacterial detection was expanded to a real-time wireless bacterium sensing system; upon NIR exposure, this nanostructure of around 100−150 nm entirely kills the bacteria. On the other hand, the detection of glucose via GOx enzyme immobilization onto polyacrylonitrile (PAN) nanofibers was reported by Çetin et al 19 The biosensors exhibited a high glucose sensitivity (92.94 and 81.72 μA/mM• cm 2 for PAN-MWCNTs/PEDOT and PAN-MWCNTs/PPy, respectively). The limit of detections (LOD) in each case were 2.30 and 2.38 μM, respectively.…”

Fast technological progress has sped up the growth of telemedicine, mobile e-health services, and healthcare monitoring, which, nowadays, are technologies in high demand in the medical field and analytical sensing. Biosensing device design has promoted forefront research topics wherein new sensing technologies have been developed. In this regard, nanomaterials have had a crucial role wherein novel biosensors based on nanomaterials have emerged as detective tools for several biomolecules. Most biosensors are remarkably sensitive and selective to detect cancer biomarkers, toxins in foods, drugs, pathogenic microorganisms, cholesterol, pesticides, nucleic acids, glucose, heavy-metal contaminations, and other bioanalytes under different platforms at extraordinarily low concentrations (nanomolar, picomolar, or femtomolar). A comprehensive review of nanomaterials used for healthcare biosensing is offered herein. Specifically, this review offers a new point of view, highlighting and covering exhaustively several kinds of nanomaterials (<500 nm) to detect human diseases through biosensing. In this sense, we organize them into organic, inorganic, and carbon-based, thus offering a guide to selecting the best nanomaterial for specific detection. Further, it provides a roadmap to the real-time utilization of nanomaterials at a commercial scale. Also, this review addresses some crucial aspects of nanomaterials use and applications for healthcare biosensing. The progress discussed in this paper highlights the immense potential to implement the use of nanomaterials and nanocomposites in the initial examination of diseases and point-of-care testing.

“…Another important application of enzymes is as biosensors, which represent advanced analytical devices with a fast response, as well as high selectivity and sensitivity in analyte detection. Sanz et al (2023) prepared novel cells that integrated biosensors based on superoxide dismutase on electrospun fibre scaffolds for the electrochemical screening of cellular stress [53], and Çetin et al (2023) prepared a compound with a highly sensitive threshold for detection of glucose via glucose oxidase immobilization on conducting polymer-coated composite polyacrylonitrile nanofibers [54].…”

Extracts from plants have been one of the main sources of antioxidants, namely polyphenols. The associated drawbacks, such as instability against environmental factors, low bioavailability, and loss of activity, must be considered during microencapsulation for a better application. Electrohydrodynamic processes have been investigated as promising tools to fabricate crucial vectors to minimize these limitations. The developed microstructures present high potential to encapsulate active compounds and for controlling their release. The fabricated electrospun/electrosprayed structures present different benefits when compared with structures developed by other techniques; they present a high surface-area-to-volume ratio as well as porosity, great materials handling, and scalable production—among other advantages—which make them able to be widely applied in different fields, namely in the food industry. This review presents a summary of the electrohydrodynamic processes, main studies, and their application.

“…Further building on the potential of conductive polymers, Chang et al developed a highly sensitive and efficient biosensor based on conductive polyaniline (PANI) and reduced graphene oxide (rGO) nanosheets ( Figure 4 d) [ 46 ]. The PANI-rGO heterostructure exhibits a remarkable sensing performance for ammonia detection, offering linear sensibility, a low limit of detection (46 ppb), and a rapid response time (approximately 75 s).…”

Triboelectric nanogenerators (TENGs) have revolutionized energy harvesting and active sensing, holding tremendous potential in personalized healthcare, sustainable diagnoses, and green energy applications. In these scenarios, conductive polymers play a vital role in enhancing the performance of both TENG and TENG-based biosensors, enabling the development of flexible, wearable, and highly sensitive diagnostic devices. This review summarizes the impact of conductive polymers on TENG-based sensors, focusing on their contributions to triboelectric properties, sensitivity, detection limits, and wearability. We discuss various strategies for incorporating conductive polymers into TENG-based biosensors, promoting the creation of innovative and customizable devices tailored for specific healthcare applications. Additionally, we consider the potential of integrating TENG-based sensors with energy storage devices, signal conditioning circuits, and wireless communication modules, ultimately leading to the development of advanced, self-powered diagnostic systems. Finally, we outline the challenges and future directions in developing TENGs that integrate conducting polymers for personalized healthcare, emphasizing the need to improve biocompatibility, stability, and device integration for practical applications.
