Bioassembly of Multicellular Spheroids to Mimic Complex Tissue Structure Using Surface-Modified Magnetized Nanofibers

The authors generated magnetized nanofibers by electrospinning magnetic nanoparticles dispersed in poly-L-lactic acid solution, which were then coated with polydopamine (PD). These PD-coated magnetic fibers had magnetic-responsive properties when incorporated into human dermal fibroblast spheroids.
