Cell viability upon THz irradiation. (A) The absolute number obtained by cell counting, while the horn was placed at different distances from the surface of the cell suspension; (B) as in (A), calculated as a proportion of viable cells with respect to the original cell concentration. (C) absolute number from the cell count, upon irradiation and without irradiation; (D) as in (C), calculated as a proportion of viable cells with respect to the original cell concentration. Cells depicted in (A,B) were suspended in PBS, and those in (C,D) in IMDM supplemented with FBS and antibiotics.
