Raises a question worth testing. It does not answer one.
This is a narrative review of magnetically responsive electrospun fibers (MREFs), an emerging biomaterial platform designed to enable post-implantation control of therapeutic delivery and mechanical properties via applied magnetic fields. The review synthesizes preclinical mechanisms and applications but reports no clinical trial data, human outcomes, or comparative efficacy evidence; current evidence is limited to feasibility and mechanistic demonstration.
Narrative review.
MREFs enable post-implantation manipulation using applied magnetic fields to generate localized heating, mechanical deformation, structural reorientation, magnetic guidance, or thermoresponsive release, unlike conventional fixed electrospun fibers Applications span cancer therapy, tissue regeneration, wound healing, and theranostics Localized and surface-accessible treatments are identified as the most realistic near-term clinical applications
No quantitative comparisons of efficacy or safety across MREF formulations or applications. Translational barriers, safety, and regulatory requirements are mentioned but not detailed with specific evidence.
This review identifies an emerging materials platform with theoretical advantages for controlled drug delivery and tissue engineering, but clinicians and researchers should recognize that no clinical trial data or human safety/efficacy evidence is presented. Current use remains investigational and preclinical.
This is a narrative review synthesizing preclinical and mechanistic evidence on an emerging material platform; it raises questions about clinical potential rather than answering them with clinical trial data.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Magnetically responsive electrospun fibers (MREFs) represent an emerging class of active soft materials designed to control where, when, and how fast a therapeutic agent or biophysical cue is delivered. Unlike conventional electrospun fibers, whose release and mechanical behavior are fixed at fabrication, MREFs can be manipulated after implantation, using an applied magnetic field to generate localized heating, mechanical deformation, structural reorientation, magnetic guidance, or triggers thermoresponsive release. This review compares MREF compositions, fabrication strategies, and magnetothermal, magneto-mechanical, and magnetic-guidance mechanisms across applications in cancer therapy, tissue regeneration, wound healing, and theranostics and critically evaluates key translational barriers, safety, and regulatory requirements. Current evidence suggests that localized and surface-accessible treatments are the most realistic near-term clinical applications.
