This study determines the effect of low-level laser therapy on SARS-CoV-2 infected HEK293/ACE2 cells and compares these cells to uninfected ones. SARS-CoV-2 infected and uninfected HEK293/ACE2 cells will be laser irradiated at different doses and the effects of laser radiation on the cells and the virus will be evaluated using luciferase assay and cytotoxicity assays.
