Production of Nanofibers from Plant Extracts by Electrospinning Method

1 Chapter Production of Nanofibers from Plant Extracts by Electrospinning Method Nilşen Sünter Eroğlu Abstract The fact that different plants grow in each climate type, that each plant has different and many benefits, and that it can obtain bio-structured, sustainable, economic, and ecological products has increased the work of researchers in this field. The long-term toxicity and harmful side effects of herbal extracts are generally less compared to synthetic drugs. Studies on the production of nanofibrous membrane structures from plant extracts are relatively limited and are an emerging field. Herbal extracts have a positive effect in electrospinning applications with their biodiversity, ability to main- tain biological functionality, and wound healing effects against pathogenic microor- ganisms. With the creation of nanofiber structures of plants obtained from natural sources, applications in fields such as wound healing, tissue engineering, drug release are increasing day by day. Keywords: nanofiber, polymer, electrospinning, herbal extract, electrospun 1. Introduction Electrospinning is the most preferred method because of its low cost compared to nanofiber production methods, production of long and continuous nanofibers, controllable nanofiber diameter, and industrial processing potential. When all these properties are evaluated, it would be appropriate to produce a nanofiber for wound healing by electrospinning. On the other hand, in recent years, interest in polymer materials obtained by the electrospinning method has increased significantly. Materials such as polymers and nanofiber composites can be produced directly by electrospinning. The post-processing of electrospun fibers forms other materials, such as ceramics and carbon nanotubes [1]. Polymer nanofibers obtained by the electrospinning method have a high surface area-volume ratio, flexible in surface functions, have superior mechanical performance, and are versatile in design [2]. Because of all these advantages, the most common and simple method used for tissue framework production is electrospinning. The principle of operation is based on filling the syringe with the polymer solution or melting in the high potential area and spraying it from the tip of the syringe to the collector by applying a voltage to an elec- trode connected to the tip of the syringe (Figure 1). Here, since the solution sprayed
