Project : Developments of Innovative DNA Photonic Devices
Research 1 Chelation of DNA with novel metals or rare earth metal compounds. Large amplifications of fluorescence light were attained in the presence of novel metal or rare earth metal cations, especially Eu or Tb showed a very large fluorescence emission with increasing amount of DNA. These results strongly suggest that electron shells would be twisted and electron state including electron spi...
متن کاملRecent Developments in Home Sleep-Monitoring Devices
Improving our understanding of sleep physiology and pathophysiology is an important goal for both medical and general wellness reasons. Although the gold standard for assessing sleep remains the laboratory polysomnogram, there is an increasing interest in portable monitoring devices that provide the opportunity for assessing sleep in real-world environments such as the home. Portable devices al...
