| 研究実績の概要 |
* We have completed the fabrication of one generation of nanodevices required for the studies, have confirmed that they are operational, and found a way to optimize the signal to noise in these sensors (publication submitted).
* We have developed a 1st version of electronics to be able to perform autonomous electrical measurements in the deep sea with nanosensors.
* We have used 3D printers to interface the high-pressure tank. With one 3D printer, we could interface the high pressure tank with microfluidic tubes and perform tests until 250 bars. We demonstrated the possibility to reduce the pressure using a long microfluidic tube, which opens the possibility to keep the box containing the sensors pressurized. For the interfacing with the electronics, we have used the PEEK 3d printer.

理由
* We are happy so far with our progress, in the sense that a first generation of devices, electronics and high pressure interfacing has been fabricated, and we could nicely interact between U.Tokyo and JAMSTEC to prepare the setup compatible with deep-sea measurements.
We have optimized some signal to noise in nanodevices.
The usage of the 3D Peek printer (compatible high-pressure and enabling the interface with the silicon chips) was not easy to operate at the begining due to very high temperatures, but we are now achieving pretty nice pieces, so we hope soon to combine everything to perform test of the whole setup containing device under high pressure.

| 今後の研究の推進方策 |
Next steps are:
* Study of rare earth elements interaction with these nanotransistors, including and finish the synthesis of the first generation of selective layers.
* Perform these tests of ion-nanotransistor interactions in the high pressure tank.
* Continue tests with the nanoelectrochemical approach.
* Progress on the automatic measurement of devices and on the 3d printed packaging.
