Biophotonics

Quantitative phase microscope applications in biological work

Quantitative phase microscope applications in biological work

The photo on the left shows three-dimensional images of human cells taken by quantitative phase microscopy. Three-dimensional shapes of intracellular and extracellular structures were acquired by detecting the very faint light reflected from the cells.

Plant growth measurement technology

We are making an attempt to measure plant growth by using light instead of relying on the knowledge and skills of experienced farmers. Information about plants acquired in this new way will be utilized along with environmental and work information to achieve smarter and more efficient agriculture.

Assessing photosynthesis by counting photons

Assessing photosynthesis by counting photons

We are studying technology to evaluate photosynthesis in plants by measuring photons emitted during photosynthesis. The technology can be used for environmental pollution assessment, plant diagnosis, and better plant breeding, that supports the production of food and the environment we live in.

Controlling cell kinetics by means of light

Controlling cell kinetics by means of light

We are also doing research on inducing dynamic changes in cells by controlling physiological activity involving an intracellular signal transducer called cAMP using a photosensitive protein (photoactivated adenylyl cyclase or PAC).

Creating sophisticated devices that utilize biomolecular machines

Creating sophisticated devices that utilize biomolecular machines

We are striving to understand how the highly sophisticated mechanisms of biomolecular machines function, with the aim of creating bio-MEMS (bio-Micro-Electro-Mechanical System) devices based on our own advanced photonics technology.
