30 December 2005 Preparation of DNA-polymer microsphere and its optical property

We succeeded to prepare the microsphere of polymer to which the marine DNA was doped. Moreover, ASE (Amplified Spontaneous Emission) was observed since the optical property of the microsphere to which the DNA was doped was discussed. In addition, an excellent optical property was found being shown in the comparison with DNA doped polymer thin film. The DNA shows a very interesting optical property like the improvement of the fluorescent intensity and the control of the concentration quenching of the dye by inserting the functional dye between the base pairs. On the other hand, the research using the surface is advanced to the microsphere for the reasons why the surface area is large. Light can be confined highly effective in the miniature space, and the microsphere of polymer is a material that is promising as optical micro cavity.
