Outline of Final Research Achievements

We developed specimen chamber, rare-earth doped nanophosphors, and new CL detection system for CL bioimaging in liquid condition. Biological CL imaging in liquid condition was achieved by developing specimen chamber having SiN thin membrane. Mono-dispersed nanophosphors with size of about 40 nm were obtained by homogeneous precipitation method using excess urea. In addition, we developed new mirror for efficient CL detection, and the mirror was mounted in SEM.
