Fluorescence images of the pH sensor and virus on the cell membrane. (A) Virus adhered to the cell surface. (B) A pH sensor adhered to the same cell with a virus on its surface, with an excitation of 470 nm laser. (C) A pH sensor adhered to the same cell with a virus on its surface, with an excitation of 532 nm laser. (D) Virus-unbound cell. (E) A pH sensor adhered to a virus-unbound cell, with an excitation of 470 nm laser. (F) A pH sensor adhered to a virus-unbound cell, with an excitation of 532 nm laser.
