Preparation of multicompartment sub-micron particles using a triple-needle electrohydrodynamic device

- Three co-axial needles are used for the first time to prepare layered polymeric particles by electrohydrodynamic forming.
- The presence of three distinct polymer layers was experimentally verified.
- The size of the layered particles prepared ranged from 220-320 nm.
- The particles prepared showed negligible cytotoxicity.
