What is the role of nanosponges in the treatment of coronavirus disease 2019 (COVID-19)?
Nanosponges for COVID-19 Treatment Nanotechnology devised an imitation of the receptors SARS-CoV-2 needs to enter human cells. According to nanotechnology experts, cellular nanosponges are derived from membranes of human lung cells and white blood cells i.e. macrophages. The combination of both is covered by ACE2 and CD147. It works by luring the SARS-CoV-2 to bind to with it like it would with real receptors. As soon as the virus binds with the nanosponge, it becomes ineffective.
