Webb[0084] In one aspect, 2 photon calcium imaging is utilized for neuronal imaging. The imaging laser source can be for example, a Mai Tai Ti: Sapphire laser (Spectra-Physics) mode locked at 920 nm for calcium imaging or at 1000 nm for structural imaging. Signals can be collected with a photomultiplier tube. The imaging system is computer controlled. WebbTransient NP loading in HPCs. The interaction of HPCs with NPs was evaluated by exposing the cells to fluorescently labeled YG-PS NPs with the concentration range of 5–90 μg mL −1.After 24 hours of continuous exposure, the cellular NP load was evaluated by measuring GMFI using flow cytometry ().HPCs displayed an almost linear loading profile …
