What is Electrospun Nanofibers in Drug Delivery Systems?

Electrospun nanofibers in drug delivery systems incorporate therapeutic agents into nanofibers produced by electrospinning for controlled release and targeted administration.

This subtopic covers encapsulation of drugs within electrospun nanofibers to achieve sustained release profiles, high surface area for loading, and tunable degradation for applications like wound healing. Key studies examine processing variables affecting fiber morphology and drug release kinetics (Pillay et al., 2013, 669 citations). Over 50 papers from 2008-2021 detail advancements in polymeric carriers like alginate and silk for biomedical delivery (Agarwal et al., 2008, 1775 citations; Ramakrishna et al., 2013, 585 citations).

Key Challenges

Why It Matters

Electrospun nanofibers enable localized drug release in wound dressings, reducing systemic toxicity and improving bioavailability (Saghazadeh et al., 2018, 788 citations). In cancer therapy, they provide sustained delivery of chemotherapeutics directly to tumor sites via high encapsulation efficiency. Agarwal et al. (2008) highlight functionalization for targeted therapies, while Pillay et al. (2013) show how processing optimizes release for chronic wounds, enhancing patient outcomes in regenerative medicine.

Key Research Challenges

Optimizing Encapsulation Efficiency

Achieving high drug loading without compromising fiber integrity remains difficult due to phase separation during electrospinning. Pillay et al. (2013) review how processing variables like voltage and flow rate impact uniformity. Ramakrishna et al. (2013) note electrospraying hybrids improve loading but scale poorly.

Controlling Release Kinetics

Balancing burst and sustained release profiles challenges biocompatibility and efficacy. Sun and Tan (2013) discuss alginate crosslinking for tunable degradation in scaffolds. Dhandayuthapani et al. (2011) emphasize polymer selection to match tissue healing rates.

Ensuring In Vivo Biocompatibility

Degradation products must not provoke inflammation during long-term implantation. Song et al. (2018) analyze biodegradable polymers for implants, citing toxicity risks. Aderibigbe and Buyana (2018) report alginate dressings succeed in wounds but face vascular integration issues.
