In this paper, various three-dimensional (3D) nanofibrous structures were constructed based on liquid support systems and alteration of the solution charge property. Structures fabricated from the liquid support system include a nanofibrous ring and spindle-shaped nanofibrous ones. The ease of fabricating fluffy, randomly organized nanofibrous structure by altering the charge capacity of the electrospun solution is also demonstrated. The set-up conditions for the design of the nanofibrous structures using these techniques are discussed.
