Two-Photon Absorbing Chromophore: Application to Microfabrication and Bioimaging |
| 초록 |
Two Photon Absorption (TPA) is a third non-linear optical process with many promising applications. In this study, some TPA compounds were synthesized and measured their optical properties in the organic solvents and water. Their TPA cross-section (TPACS) were measured by using fluorescence two-photon excitation method in each solvent. The TPACS of EMPA-4Branch showed highst value in both solutions. Compounds were applied for the 3D microfabrication and bioimaging, and each results were compared on the basis of the compounds TPACS. Images of Hela cell incubated with PASN nanoparticles and EMPA-4Br solution were obtained to demonstrate the potential for bioimaging. And the 3D microstructures were made by SU8 resin containing EMPA and EMPA-4Br. And also after finishing process of EMPA's derivatives, it will apply to microfabrication with SU8. |
