Outline of Final Research Achievements |
We proceeded experiment toward development of “Superresolution chemiluminescence holographic microscopy” enabling chemiluminescence image acquisition with high speed, three-dimension and superresolution quality, by applying chemiluminescent protein with Fresnel incoherent correlation holography (FINCH) and wavefront correction system. By observing HeLa cells expressing chemiluminrescent protein “Nano-lantern” using FINCH, we could reconstruct the chemiluminescent tomographic images with as good quality as the fluorescence ones. To correct wavefront distortion of light, we constructed a wavefront correction system and evaluated the superior performance. To achieve high speed and multi-color acquisition of the chemiluminescent holograms, we developed color palettes of chemiluminescent protein “eNano-lantern” with approximately 10-fold improvement in the brightness compared with previous Nano-lantern.
