24 Oct Applications of Electrospinning Nanofibres in Agriculture
कृषि में इलेक्ट्रोसपिनिंग नैनोफिब्रिज के अनुप्रयोग Nanofibres are able to form a highly porous mesh and their large surface-to-volume ratio improves performance for many applications. Electrospinning has the unique ability to produce nanofibres of different materials in various fibrous assemblies. Electrospinning was first patented in the US in 1902. However, the process was largely forgotten until the 1990s. With interest in the field of nanoscience and nanotechnology, researchers began new investigations of nanofiber production using electrospinning (Seeram et al. 2006). The number of patents and applications for processes and applications based on electrospinning has also grown in recent years. Types of Electrospinning Although fibers produced by different electrospinning methods have attracted increasing attention in the field of biomedical applications, challenges persist for the selection of an appropriate method, as well as for optimizing multiple parameters to generate robust cargo loaded nanofibres. Electrospinning techniques can be classified into five categories: Blend electrospinning Coaxial electrospinning Emulsion electrospinning Melt electrospinning Gas jet electrospinning Blend electrospinning can be used to develop nanofibres with burst release, while co-axial and emulsion electrospinning can be used to generate core-shell nanofibres that can assist in sustained drug release. Melt electrospinning is a cleaner fabrication method that has been used extensively to produce highly ordered electrospun nanofibres. However, melt electrospinning results in the generation of fibers with a larger...
