Abstract: Non-viral nucleic acid delivery agents and methods for the delivery or transfer of nucleic acid molecules to target cells are disclosed. The agents comprise a complex of a nucleic acid cargo for delivery, one or more lipopeptide compound, and one or more polymeric charge-neutralising agent, and the complex is in the form of a particle with substantially neutral or negative surface charge. The agents and methods may be useful in a variety of applications such as therapies (including gene therapies and nucleic acid vaccinations) for diseases and medical disorders.

Abstract: A device is provided which is suitable for delivering at least one nanoparticle(s) to a subject. The device can be used to deliver a variety of nanoparticles, for example, therapeutic agents, directly through the outer layers of the skin without passing completely through the epidermis of the subject. Thus the device can be used to deliver therapeutic agents to a predetermined depth and avoid disturbing the pain receptors in the skin. Thus the device can be used to deliver agents, including therapeutic agents, in a non-invasive manner. A method of fabricating devices with associated nanoparticles is also provided.
