Abstract
Over the past few decades, the engineering of helical, spring, curled, and hierarchically structured
nano/microfibers has attracted considerable attention due to their unique characteristics and potential
applications in tissue engineering and various industrial fields. Understandin g the parameters and
processes involved in the fabrication of these fibers is essential. This comprehensive review outlines
recent advancements in research on helical nano/microfibers, focusing on processing techniques, fiber
structure, and property characterization, and their applications in fields such as tissue engineering and
regenerative medicine. The study also investigates the mechanical and hydrodynamic parameters that
influence the fabrication of helical fibers using contemporary techniques. It hig hlights that helical
structures form when electric and elastic forces are balanced due to non -uniform electric fields. The
coaxial electrospinning technique, along with the use of polymers with varying elastic and conductive
properties, plays a crucial role in producing these structures. The distinctive properties of helical
nanofibers, such as their mechanical strength, high porosity, biocompatibility, and ability to promote
cellular activities, make them promising candidates for developing scaffolds in bo ne tissue engineering.
