Magneticassembly of microfluidic spun alginate microfibers for fabricating three

Microfluidicdevices employed as "printing" head provide a mild condition tofabricate cell-laden hydrogel modules for three-dimensional (3D) assembly tocreate cellular constructs. However, because of the poor controllability of hydrogelsand unstable microfluidic fabrication process, it remains a challenge tofabricate morphologically accurate structures to mimic in vivo tissues, which hindersthe bui
