Figure Lengend Snippet: (A) Schematic of the inverted widefield frequency-domain FLIM system used for live oxygen measurements. The setup includes a 470-nm high-power LED under external modulation, an inverted fluorescence microscope with appropriate excitation/emission filters (Ex 420–490 nm/Em 570–670 nm), and a dual-tap FLIM camera for multi-phase acquisition. (B) Confocal image of a cerebral organoid after 26 days in culture, stained with CellMask (green) to delineate tissue architecture and to localize the oxygen-sensitive CPOx microbeads (red). Scale bar: 100 μm.
