Embodiments of the present disclosure pertain to methods of detecting a thiol in an environment by exposing the environment to a probe molecule that contains a marker and a thiol responsive group. The thiol responsive group reversibly reacts with the thiol in the environment to form a probe-thiol adduct. This in turn causes a ratiometric change in a spectrometric property of the probe molecule and the probe-thiol adduct, which can then be correlated to the presence of the thiol in the environment. The correlation can occur by quantifying the thiol concentration in the environment. In addition, thiol detection can occur in real-time. Further embodiments of the present disclosure pertain to probe molecules that are utilized for detecting a thiol in an environment. In some embodiments, the probe molecule includes a marker and a thiol responsive group. In some embodiments, the probe molecule also includes an organelle targeting moiety.
