Sustainable biomedical microfibers from natural products

Abstract Microfibers from natural products are endowed with remarkable biocompatibility, biodegradability, sustainable utilization as well as environmental protection characteristics etc. Benefitting from these advantages, microfibers have demonstrated their prominent values in biomedical applications. This review comprehensively summarizes the relevant research progress of sustainable microfibers from natural products and their biomedical applications. To begin, common natural elements are introduced for the microfiber fabrication. After that, the focus is on the specific fabrication technology and process. Subsequently, biomedical applications of sustainable microfibers are discussed in detail. Last but not least, the main challenges during the development process are summarized, followed by a vision for future development opportunities.
