Abstract
A key challenge in the production of multicomponent nanoparticles for healthcare applications is obtaining reproducible monodisperse nanoparticles with the minimum number of preparation steps. We report the engineering of novel electrosprayed core-shell polymer-lipid nanoparticles as an active component delivery platform, with high active component encapsulation efficiency, tunable and sustained active component release profile, excellent stability, and potential for active component nanoencapsulation and delivery applications. The nanoparticles comprise two distinct functional components: (i) a hydrophobic polymeric core wherein poorly water-soluble active components can be encapsulated; (ii) an amphiphilic lipid monolayer shell which acts as a molecular barriercontrolling active component release. The physicochemical properties of the nanoparticles including size and electrical conductivity are controlled by varying the composition and concentration of the precursor materials and the electrospraying process parameters. In vitro testing indicated that nanoparticle size and active component loading had the greatest influence on the release rate. This method for preparing hybrid nanoparticles in a single step may be useful for combinatorial synthesis of nanoparticles with different properties for active component delivery applications.
