Abstract
A method of exciting an organic salt in a cell is provided. The method includes contacting the cell with a composition including the organic salt, the organic salt having a photoactive ion and a counterion. The cell uptakes the organic salt, the organic salt is substantially free of a coating within the cell, and the organic salt is non-toxic to the cell in the dark. The method also includes exposing the cell to light having a first wavelength, wherein the organic salt absorbs the light having the first wavelength and the photoactive ion becomes excited.
