The photophysical properties of fluorescent dyes have been investigated in confined and crowded reverse micellar environments in presence and absence of graphene oxide nanocolloids. Various steady-state and time-resolved spectroscopic techniques such as UV-Vis absorption, fluorescence emission and other complimentary spectroscopic techniques were employed to understand electronic and hydrodynamic properties of the probe molecules in both cationic and anionic reverse micelles. The effect of graphene oxide nanocolloids on photophysics of the probemolecules were investigated. The results obtained in confined environments were compared with the results in aqueous environments. Our experimental observation shows that the fluorescent probemolecules behaves very differently in reverse micellar environment as compared to aqueous environment. Since reverse micelle mimics the cellular environment, our findings can be used as a protocol to study biomolecule dynamics inside confined reverse micellar environment by using reverse micelle as a simple model system.
