“…Based on the obtained optimized conditions, the effect of treatment on the secondary structures of SARS-CoV-2 spike protein and another model protein RNase A was studied. RNase A is a structurally versatile and highly stable protein having 124 amino acid residues [24] , [25] . The main focus of the present work is to provide an inexpensive and efficient disinfection method by combining IR and UV-C irradiations to fight against contagious infections by viruses and bacterial pathogens.…”
