WebJul 13, 2024 · Concentration range was between 0.05 – 0.40 µM. Quantum yield and fluorescence lifetime for sensor 40 is 0.294 and 1.944 ns respectively. Based on the pH effect on fluorescence change, pK a value of 40 was found to be 6.94, which is due to the strong electron donating ability of the morphine group in the sensor. WebThe method involves fluorescently labeling peptide molecules that would alter an organism's natural pathway. When this peptide is inserted into the organism's cell, it can induce a different reaction. This method can be used, for example to treat a patient and then visibly see the treatment's outcome.
