Novel technology developed at Spheritech for drug delivery uses self assembled natural fatty acid microparticles for immobilization of proteins, enzymes antibodies, RNA and DNA also provides an optimum delivery system for vaccines. These microparticles, termed SpheriSomes, currently under investigation for mucosal delivery have been tailored to carry a positively charged GRAS approved peptide which facilitates adhesion to negatively charged mucus. This technology is protected by granted patents and Spheritech are seeking partners to develop the next ground breaking technology in Vaccine delivery.
