摘要：
In this work, we demonstrate the use of Two-Photon Fluorescence Lifetime Imaging Microscopy (TP-FLIM) for intracellular calcium ([Ca2+](i)) measurement with a calcium sensitive fluorescent dye in a neuronal cell model and brain tissue. Calcium perturbations were induced via chemical stimulation and our results signify the potential of TP-FLIM for quantitative ([Ca2+](i)) measurement within the physiological range of intracellular [Ca2+].
