| Research Abstract |
In this study, we performed the chemical design of the arrangement of metallic nanoparticles and the shape of nanostructures for aiming at the development of highly sensitive optically-driven biosensor, the local temperature sensor and so on. As a fundamental achievement, it has been clarified that linear and nonlinear optical responses can be significantly enhanced by fixing metallic (Au or Ag) nanoparticles densely onto a plastic bead with binder molecules. Also, in the similar system, we have revealed that the optical control of heat coagulation, and we have obtained an important knowledge for the development of temperature sensor based on the optical detection in nano- and micro-spaces. Furthermore, we have clarified that light scattering decreases or increases at particular wavelength regions by binding heterogeneous metallic nanostructures via DNA. This result indicates the possibility that a small amount of DNA less than amol can be detected even by white light irradiation.
