| Research Abstract |
High sensitive matter detection is possible by applying antigen-antibody reaction, one of the biochemical sensing methods. However, fluorescence microscope and/or other analysis equipment are required and the system tends to be complicated. This study aims to simplify such system by combining fluorescent intensity improvement by nano-/microstructuring produced with self-assembly of fine particles on an optical lens and its condensation effect. It was found that the fluorescent intensity was improved up to 6 times compared to a planer substrate without fine structure. However, the improvement is limited by the scattering effect of the fine structure.
