TWO-PHOTON FLUORESCENCE EXCITATION CROSS-SECTIONS OF PHOTOSENSITIZER THIOXANTHONETO FABRICATE CELL SCAFFOLD FOR BIOMEDICAL APPLICATIONS

This study investigates the fluorescence emission profile of Thioxanthone in ethanol due to two photon absorption excitation. Thioxanthone was investigated as photosensitizer to fabricate cell scaffold in Ethoxylated Bis Phenol A Dimethacrylate for tissue repair in the field of biomedical. Also incident laser power effects were analyzed and it was found that the fluorescence intensity increases with increasing incident laser power, I o ,and the emitted fluorescence obeys the square-law dependences. Also when the photosensitizer was excited at different wavelengths (800nm, 400nm), it was found that fluorescence emission profile does not change but variations occur only in fluorescence emission intensity This study investigates the fluorescence emission profile of Thioxanthone in Ethanol due to two photon absorption excitation.  Thioxanthone  was  investigated  as  Photosensitizer  to  fabricate  cell  scaffold  in  Ethoxylated  Bis  Phenol A Dimethacrylate  for  tissue  repair  in  the  field  of  biomedical.  Also  Incident  Laser  Power  Effects  were  analyzed  and found that the Fluorescence Intensity increases with increasing Incident Laser Power, Io, and the emitted fluorescence obeys  the  square-law  dependences.  Also  when  the  Photo-Sensitizer  was  excited  at  different  wavelengths  (800nm, 400nm), it was found that Fluorescence Emission Profile did not change but variations occurred only in Fluorescence Emission Intensity.
