Insights into the phenomenon of acquisition and accumulation of Fe3+ in Hygrophila spinosa through fluorimetry and fluorescence images

摘要

Rhodamine functionalized fluorescent probe IP has been synthesized to investigate the phenomenon of Fe3+ acquisition and accumulation in Hygrophila spinosa. H. spinosa is a tropical medicinal plant which is iron rich and consumed for the treatment of the patients suffering from anaemia. IP is capable of selectively binding Fe3+ by enhancing fluorescent intensity via "turn on" mechanism due to complex formation. Spectroscopic studies and microscopic tools helped in better understanding about the acquisition as well as the quantitative accumulation of Fe3+ in different parts of the plant.
