I found the field of Chemistry very interesting. Saw the article A simple coumarin based fluorescent On probe for the selective detection of Al3+ along with its application in live cell imaging via AGS cell line published in 2020.0. Product Details of 91-02-1, Reprint Addresses Mondal, TK (corresponding author), Jadavpur Univ, Dept Chem, Kolkata 700032, India.; Murmu, N (corresponding author), Chittaranjan Natl Canc Inst, Dept Signal Transduct & Biogenis Amines STBA, Kolkata 700026, India.. The CAS is 91-02-1. Through research, I have a further understanding and discovery of Phenyl(pyridin-2-yl)methanone
A new coumarin based fluorescent switch (HCBP) has been fabricated which displays high selective sensing towards Al3+ among other metal cations at physiological pH. On gradual addition of Al3+ specifically, HCBP shows a brilliant turn-on emission enhancement of about similar to 13-fold with about 50 nm red shift at 481 nm in MeOH/H2O (1/1, v/v) solution. The fluorescent switch is proven to be a reversible probe by addition of EDTA gradually into the HCBP-Al3+ solution. Detection limit as well as Binding constant values have been calculated and found to be in the order of 10(-9) M and 10(3) M-1 respectively. DFT and TDDFT studies are conducted with the probe to establish a similarity between theoretical and experimental outcomes. We can also use this new fluorescent switch as a biomarker kit as it has shown a brilliant potential in the application of live cell imaging using gastric cancer cell (AGS cell).
