their long-term efficacy is often undermined by the high mutation rate and rapid emergence of drug resistance [3]. Besides, the constant emergence of new viruses and the increasing frequency of pandemic outbreaks underscores the urgent need for the broad-spectrum anti-virals [4,5]. At present,...
Spectroscopy (XPS) investigation was performed on the materials using a Thermafischer scientific Nexsa base system to get insight into their chemical composition and bonding states. To record the absorbance spectrum, UV–visible (UV–Vis) spectroscopic data were obtained using a GENESYS 10S UV–...
