Abstract
Three TRIS-based molecular probes, L1/L2/L3, were screened for their ability to detect Zn2+ at nanomolar level. Keeping in mind the criteria for a molecular probe to be utilized as bioimaging material, L2 was chosen as model compound for biological studies due to its higher excitation/emission wavelengths. While investigating the potential of L2, intracellular Zn2+ was successfully imaged using fluorescence microscopy. As the fluorescence emission of L2-Zn2+ ensemble was stable for longer duration, more than 3h, L2 was successfully utilized in in-vivo imaging of Zn2+ in a whole plant (Peperomia pellucida) in real time. Further to its in vivo imaging capability, L2 was found to be successful in imaging zinc pool of gram seed sprouts.
