Azide Functionalized Porphyrin Based Dendritic Polymers for In Vivo Monitoring of Hg2+ Ions in Living Cells
mercuric ion in living (normal and cancer) cells, and in aqueous medium. The developed sensor could sense mercuric ion even in the nanomolar concentration with the limit of detection value of 0.9 nM. This probe can be used to monitor mercuric ion in living cells due to its low cytotoxicity and high cell permeability. The hydrophilic nature of the polymer makes it a promising candidate for sensing mercuric ion in real water samples. Moreover, the reversibility of this sensing strategy helped to construct a logic gate, which is specifically useful in smart sensor design.
