Transparent light detection devices are attractive for emerging see-through applications such as augmented reality, smart windows and optical communications using light fidelity (Li-Fi). Herein, we present flexible and transparent photodetectors (PDs) using conductive poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS): Ag nanowires (NWs) based nanofibres and zinc oxide (ZnO) NWs on a transparent and degradable cellulose acetate (CA) substrate. The electrospun (PEDOT:PSS): Ag NW-based nanofibres exhibit a sheet resistance of 11 Ω/sq and optical transmittance of 79% (at 550 nm of wavelength). The PDs comprise of ZnO NWs, as photosensitive materials, bridging the electrode based on conductive nanofibres on CA substrate. The developed PDs exhibit high responsivity (1.10 ×10 A/W) and show excellent stability under dynamic exposure to ultraviolet (UV) light, and on both flat and curved surfaces. The eco-friendly PDs present here can degrade naturally at the end of life - thus offering an electronic waste-free solution for transparent electrodes and flexible optoelectronics applications.

Hydrogel-based solar interfacial evaporators, featuring various channels such as random, unidirectional, and radial array, are considered effective for seawater desalination owing to their porous structure, lower evaporation enthalpy, and controllable water transport capacity. However, each individual array structure has its own strengths and limitations, influencing water transportation, thermal management, and salt rejection. By combining the benefits of each array configuration into a single evaporator, the evaporation performance can be maximized.

Wearable, non-invasive sweat sensors capable of continuously monitoring the pH of sweat, which is a key indicator related to metabolism and homeostasis level, are highly desirable for personal health management. However, ensuring the stability and accuracy of these sensors can be challenging when the body is in motion. In this work, we prepared a stretchable nanofibrous membrane-based electrochemical pH-sensing electrode by embedding carbon nanotubes (MWCNT) and silver nanowires (AgNWs) into an elastic electrospun nanofibrous membrane, followed by polyaniline electrodeposition.

Positive surgical margins following radical prostatectomy significantly contribute to tumor recurrence. While systemic chemotherapy demonstrates limited efficacy in this context, local chemotherapy drug delivery systems based on nanomaterials offer promising strategies to address this issue by modifying drug release kinetics and distribution, thereby enhancing antitumor effects while minimizing the toxicities associated with systemic chemotherapy. In this study, we utilized electrospun nanofibrous mats loaded with docetaxel for sustained drug delivery.

Intensively studied polymeric particle production technologies often rely on the combination of polymer self-assembly and particle processing techniques. Herein, an elegant crystallization transition-mediated strategy is proposed to confine molecular self-assembly within a limited range, avoiding the need for extra particle processing steps. This approach enables the production of the regenerated nanofibrous chitin clusters woven with the helical nanofibers.
