Abstract: Electrospun nanofibers have the characteristics of extremely fine diameter, high specific surface area, and good pore structure. They are easy to operate, low costing, and mass-producible. Their unique structure and performance have received widespread attention in the field of drug delivery. In recent years, the application of electrospun nanofibers in the field of drug delivery has made further research breakthroughs. By controlling the diameter and shape of the fibers, efficient drug loading and sustained release can be achieved, and drug bioavailability and reducing toxic side effects can be enhanced. These properties expedite the application prospects of electrospun nanofibers in drug delivery.
In recent years, electrospun nanofibers have been widely used in the field of drug delivery. Their nanoscale diameter and porous structure make electrospun nanofibers an ideal drug carrier material. Biodegradable polymer nanofiber membranes can not only stably carry various types of drugs, but also achieve slow drug release, thereby improving drug efficacy and reducing side effects. Compared to traditional drug delivery systems, electrospun nanofibers have many advantages. Firstly, their nanoscale diameter and porous structure are beneficial for improving the solubility and bioavailability of drugs, enhancing their stability and bioavailability efficiency. Secondly, electrospun nanofibers can simulate the natural extracellular matrix structure, provide a scaffold for cell adhesion, and help promote tissue regeneration and healing. In addition, electrospun nanofibers can also achieve controlled drug release, further improving the therapeutic effect of drugs.
Research and development based on pharmaceutical technology is the foundation for enhancing the development of drug delivery. Research has confirmed that electrospun nanofibers, as drug carriers, have become a hot research topic in the field of drug delivery for local drug delivery and slow release drug systems in the treatment of diseases. By encapsulating drugs within electrospun nanofibers, not only can the solubility and stability of drugs be improved, but the duration of sustained drug release can also be extended, local drug concentration can be increased, and treatment effectiveness can be improved. This technology has shown great potential for application in multiple drug delivery fields such as anti-infection, wound healing, and anti-cancer.
The development trend of electrospun nanofibers in the field of drug delivery mainly includes multifunctionality, intelligence capabilities and precision. With the continuous development of nanotechnology and materials science, electrospun nanofibers will be more widely used in drug delivery systems and can achieve more diverse functions. In the future, with the continuous progress of medical technology and the development of interdisciplinary fields, electrospun nanofibers as carriers of drug delivery systems are expected to achieve more precise drug treatment, bringing revolutionary changes to the medical field. Electrospun nanofibers, as a cutting-edge technology in the field of drug delivery, will continue to bring new hope and possibilities to the medical and pharmaceutical fields.
