Respiratory infections by RNA viruses are one of the major burdens on global health and economy. Viruses like influenza or coronaviruses can be transmitted through respiratory droplets contaminated surfaces. An effective antiviral coating decrease viability virus particles in our surroundings significantly, hence reducing their transmission rate. Here, we have screened a series nanoparticles composites for activity using nanoluciferase-based highly sensitive A reporter virus. We identified...
