Iranians Patent Nano Wound Dressing

Iranian pharmacists, who invented a nanostructured wound dressing that leads to speedy healing with antibacterial agents, were granted a US patent.

“Our invention is a skincare gel containing pectin nanoparticles, wound healing and anti-microbial agents. The proposed wound dressing involves positively or negatively charged polymers that cover and protect the wound surface,” said Dr. Rassoul Dinarvand, professor and the head of Faculty of Pharmacy and Medical Nanotechnology Research Center at Tehran Medical University, Fars News Agency reported.

The nanoparticles enable a controlled release of the antimicrobial agent to the wound efficiently, which expedites the healing process and makes it much easier.

“A very simple and straightforward technique has been adopted to prepare pectin nanoparticles attached by the desired wound healing agents. 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 that disrupts peptides and proteins in general,” he said.

As the active ingredients of this product are enclosed inside a specific nanostructure, their release is controlled and obeys a pseudo-zeroth-order kinetics. This makes it a superior feature of the method.

Dr. Dinarvand thanked the Iran Nanotechnology Initiative Council for its financial support for the patenting process and stated that the council’s policies are encouraging Iranian inventors to patent their innovations globally.
