Features of Nanofiber Manufacturing Strategies

Strategy	Self-Assembly	Phase Separation	Electrospinning
Status	Semi-solid	Solid	Solid
Physical shape	Hydrogel	Scaffold	Scaffold
Size (nm)	5–20	50–500	50–2000
Benefits	Absence of biohazardous solvents 3D structure	Simple process Better control of pore size 3D Shape	Single manufacturing process Ability to control the pores
Limitations	Complex process Expensive	Absence of control over the internal structure	Inability to conform the 3D architecture.
