Outline of Final Research Achievements |
Optogenetics is an innovative neuroscience method to control the neural activity even in a living animal. The near infrared (NIR) light (wavelength, 650-1450 nm) penetrates deeper in tissues than the visible light, and is a candidate signal to the brain from outside of the body. However, there have not been the tools to catch the near infrared signal for optogenetics. The lanthanide nanoparticles (LNPs), composed of rare-earth elements, absorb low-energy NIR light to emit high-energy visible light (up-conversion). We created a hybrid optogenetic system which consists of the donor LNPs and the acceptor ChRs which are highly sensitive to the emission wavelengths of LNPs. When the NIR laser light was applied to nearby LNPs, the membrane potential was depolarized to evoke action potentials. It is suggested that the green luminescent light emitted from UCNPs effectively activated ChRs to generate enough large photocurrent to change neural activities even in the living animal.
