Virucidal Coatings Using Layer-by-Layer Film Technology

As we know, layer- by -layer (LBL) assembly is a very versatile and robust technique in creating thin films with highly adjustable properties. Many different types and shapes of surfaces can be coated with this technology. My research topic focuses on creating surfaces via LBL technique with the ability to inactivate human viruses, especially the various pathogenic strains of influenza viruses. The project is funded by the Institute for Soldier Nanotechnologies (ISN), and is in collaboration with Professor Alexander Klibanov in the Department of Chemistry and Professor Jianzhu Chen in the Department of Biology at MIT. The project builds on previous four years of ISN research focused on creating new, non-leaching bactericidal and fungicidal surfaces. LBL film as we know it is very robust and adhere to surfaces very well. The focus of the project is to create virucidal coatings which will dramatically reduce the spread of influenza and possibly other pathogenic viruses’ infections in the battlefield. These coatings can be used to coat surfaces like weapons, equipments, uniforms, personal item, filters and so on. A small reduction in the chances of influenza infections will greatly enhance the readiness and performance of soldiers and other military personnel.
