What is Electrospun Nanofibers in Biomedical Applications?
Electrospun nanofibers in biomedical applications refer to ultrathin polymer fibers produced via electrospinning and employed in tissue engineering, drug delivery, and regenerative medicine.
Electrospinning generates nanofibers from polymers, composites, and ceramics for biomedical uses including scaffold design and nanocomposites, as detailed in 81,758 works. "A review on polymer nanofibers by electrospinning and their applications in nanocomposites" by Huang et al. (2003) covers techniques and nanocomposite integration.

Why It Matters
Electrospun nanofibers support tissue engineering by mimicking extracellular matrix structures for cell growth, as foundational principles in "Tissue Engineering" by Langer and Vacanti (1993) apply to nanofiber scaffolds. In drug delivery, they enable controlled release through nanocomposite designs reviewed in "A review on polymer nanofibers by electrospinning and their applications in nanocomposites" by Huang et al. (2003), with 7,410 citations demonstrating impact. Alginate-based electrospun systems combine with hydrogels for regenerative medicine, building on "Alginate: Properties and biomedical applications" by Lee and Mooney (2011), which details biocompatibility in wound healing and scaffolds, evidenced by 7,479 citations.
