Abstract One-dimensional nanostructures are used in many fields such as sensor technologies. Nanosized fibers used in sensor production are nanostructures that meet the needs of different usage areas with their advantages such as high mechanical properties, significantly high surface areato-volume ratio, and small pore sizes. The quest for sustainability in industries is increasing interest in natural fibers. Particularly, the environmental impacts and sustainability shortcomings of glass fiber and polymer-based fibers have spurred the search for alternative materials. Natural fibers are fibers derived from plant-based materials and generally possess biodegradable or recyclable properties. [ Agarwal, B.,2006] Industries are in search of lighter and environmentally friendly materials. Natural fiber-reinforced composites are seen as a suitable option to meet this need. These composites leverage the advantages of natural fibers, such as their lightweight, low density, renewable sourcing, and recyclability, while also providing high strength and durability. [ Rowell, R., 2008] To create the targeted sensing layer of the biosensor, a sponge-like product obtained by drying a squash species from the Cucurbitaceae family, also known as sponge gourd or luffa, is used along with metal oxide (TiO2) and polyaniline (PANI) to form an organic structure with semiconductor properties and high biodegradability. Firstly, cellulose obtained from squash fibers through an alkaline treatment process. Then, it is mixed with PANI, selected due to its high electrical conductivity, suitability for doping, and low cost, to obtain a natural fiber-based biocomposite [Laidani, Y., 2012]. In the final stage, TiO2 is added to impart semiconductor properties to the biopolymer. The electrospinning method, which is the most preferred technique in nanofiber production, has been utilized in the fabrication of the bio-composite nanofiber structure representing the sensing layer. These bio-composite nanofiber sensing layers have been produced and optimized under different parameters via the electrospinning method. Subsequently, bio-composite nanofiber sensing layers containing different ratios of metal oxide and cellulose were characterized using analysis methods such as X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and Differential Scanning Calorimetry (DSC). The results obtained from the characterization methods mentioned above are consistent with the literature. The newly produced bio-composite material proposed at the conference will be presented along with the obtained data and analyses.
