Systems and Methods for Forming Nanocapsules by Pulsed Electrospraying

Disclosed herein are nano-encapsulated compositions and systems and methods of preparing the same. The compositions may be obtained through co-axial electrospraying with pulsating voltage. The nano-encapsulated composition exhibit improved pharmacokinetic properties. Various embodiments include systems and methods that apply a constant voltage and/or a pulsating voltage at a frequency to a plate having co-axial outlets through which a core solution and capsule solution flow. In some implementations, the pulsating voltage fluctuates between a minimum pulsating voltage and a maximum pulsating voltage, wherein the minimum pulsating voltage is 0 KV or greater and the maximum pulsating voltage is greater than 0 KV and the minimum pulsating voltage. The constant voltage is greater than 0 KV, and a total maximum applied voltage to the plate is the sum of the maximum pulsating voltage and the constant voltage.
