Iranian pharmacists invented a nanostructured wound dressing which comprises active wound healing and antibacterial agents. The innovative method and its related product was granted a US patent on July 19, 2012.
"Our invention is a skin care gel containing pectin nanoparticles, wound healing and anti-microbial agents. The proposed wound dressing involves positively or negatively charged polymers which cover and protect the wound surface. The employed nanoparticles enable a controlled release of the wound healing agent or the antimicrobial agent to the wound efficiently in course of time," Dr. Rassoul Dinarvand, PhD in pharmaceutics, Professor and Head of Faculty of Pharmacy and Medical Nanotechnology Research Center at Tehran University of Medical Sciences, told INIC.
"As a result, the wound healing process becomes faster and much easier by this method."
"A very simple and straightforward technique has been adopted to prepare pectin nanoparticles attached by the desired wound healing agents," he said, adding, "This synthesis method is solvent-free and, in contrast to the conventional methods used for the production of nanoparticles, does not entail sonication or homogenization which disrupts peptides and proteins in general."
"As the active ingredients of this product are enclosed inside a specific nanostructure, their release is well under control and obeys a pseudo-zeroth-order kinetics," Dr. Dinarvand said, underscoring the controlled release mechanism as a superior feature of the method.
He also appreciated the INIC for its financial support for the patenting process of the novel method, and stated that the INIC's financial incentive policies are most effectively encouraging Iranian inventors to patent their innovations globally.
