Liposomes, a novel drug delivery system (NDDS), are bilayer vesicular structures used in delivering drugs or genetic material into a cell. The aim of NDDS is to deliver the drug at a rate directed by the needs of the body during the period of treatment. Due to the growing number of COVID-19 patients, especially in the US and the European countries, research institutes are pressurized to accelerate their R&D activities to develop drugs and vaccines for the treatment.
