This study investigates the use of easily accessible nano-biological materials with color change capabilities, antioxidant properties, and antibacterial characteristics. Utilizing electrospinning technology, curcumin-loaded composite elastic polyurethane nanoparticles were prepared and successfully integrated into pre-combed cotton web through a spraying and bonding process. Subsequently, the yarn was produced using traditional spinning methods, including coarse and fine yarn spinning. Cotton webs loaded with varying curcumin contents (1%, 2%, 3%, and 4% by mass) were successfully formed at a feed rate of 60 mm/s. The micro-morphology, macro properties, and functional characteristics of these webs were examined post-yarn spinning at 25 °C and a relative humidity of 60%. Scanning electron microscopy observations indicated that as the curcumin loading content increased, the distribution of curcumin nanoparticles on the cotton fiber surface became more uniform. This research seeks to address the effective loading of curcumin nanoparticles into yarn and to explore the impact of curcumin content on the properties of the resultant yarn. © The Author(s), under exclusive licence to the Korean Fiber Society 2025.

The development of physiology and neurological diseases is normally accompanied by the production of acidic changes, making it crucial to develop biosensing system to detect pH variations to prevent early organ lesions. Due to the electrical double layer at the electrolyte/nanowire interface, artificial synaptic transistors can sensitively detect the pH variations. However, few studies focus on monitoring pH variations of the body based on synaptic transistors. In this study, electrolyte-gated synaptic transistors were fabricated using zinc tin oxide (ZnSnO) nanowires as channel materials. The fabricated devices can successfully mimic the functionality of acid-sensing ion channels (ASICs) in biological synapses, including excitatory postsynaptic currents (EPSCs), paired-pulse facilitations (PPFs), and short-term potentiations (STPs) under acidic conditions. Furthermore, 3× 3 ZnSnO synaptic transistor arrays were constructed to monitor acid stimulations of diverse intensities and different regions to mimic the tongue ability of human. This work can not only advance the understanding of ASIC functionality in artificial synaptic devices, but also provide a novel approach to develop bioinspired taste-sensing systems with integrated sensing and memory capabilities. © 1980-2012 IEEE.
