Protein nanowires exhibiting specific biological activities hold promise for interacting with living cells and controlling and predicting biological responses such as apoptosis, endocytosis and cell adhesion. Here we report the result of the interaction of a single high-energy charged particle with protein molecules. Degradation of the human serum albumin nanowires was examined using trypsin. The biotinylated human serum albumin nanowires bound avidin, demonstrating the high affinity of the nanowires. Human serum albumin-avidin hybrid nanowires were also fabricated from a solid state mixture and exhibited good mechanical strength. The biotinylated human serum albumin nanowires can be transformed into nanowires exhibiting a biological function such as avidin-biotinyl interactions and peroxidase activity. The present technique is a versatile platform for functionalizing the surface of any protein molecule with an extremely large surface area.

The big tsunami wave caused by the Great East Japan Earthquake triggered station black out of the Fukushima Daiichi Nuclear Power Plant. The schedule until ending of the decommission is shown in the guidance from Japanese government. But the dose rate in the reactor vessel is quite high and it is not possible to specify the position of melted fuel debris by visual inspection. That is one of the most important issues in this process. This report describes the development of Self Powered Gamma Detector (SPGD) for the purpose to specify the position of melted fuel debris and situation in the reactor by measuring $$gamma$$ rate in the reactor of the Fukushima Daiichi Nuclear Power Plant. The $$gamma$$ irradiation examinations by changing the parameter of emitters figure were performed and the dependency of SPGD output on emitter shape was summarized.

A multi-reflection time-of-flight (MRTOF) mass spectrograph has been implemented at RIKEN to provide high-precision mass measurements of very short-lived nuclei. Of particular interest are mass measurements of r-process nuclei and trans-uranium nuclei. In such nuclei, the MRTOF can perform on par with or better than traditional Penning trap systems. We demonstrate that the MRTOF-MS is capable of accurately attaining relative mass precision of $$delta$$m/m $$<$$ 10$$^{-7}$$ and describe it's utility with heavy, short-lived nuclei.

We have developed the ETCC for new medical imaging device and succeeded in imaging the some medical imaging reagents. Thus, this detector is thought promising for a new medical imaging. The F-18 point-like and rod-like phantoms are measured with new ETCC, and the imaging performance was estimated. In addition, measurement of Tc-95m which is produced by Japan Atomic Energy Agency was performed.

SPECT and PET are widely used for medical imaging. However, radio isotopes available for SPECT and PET are limited. Under these circumstances, it is expected the appearance of the new $$gamma$$ imaging detector which can measure more various kinds of $$gamma$$-ray sources in order to develop new biomarkers using new radio isotopes. We set out to contribute to medical imaging technology by developing Electron-Tracking Compton Camera (ETCC) which can measure the various radioactive medicine.

We present the performance results using this new ETCC such as the imaging test using F-18 in point-like and rod-like phantoms with varying the intense of radiation. In addition, the measurementof Tc-95m which is produced by Japan Atomic Energy Agency was performed. Tc-95m emitsthe $$gamma$$-rays with the energy, 204, 583, and 835 keV, and then an image with multi-energies is examined. The position resolution achieves less than about 8 degrees from 10 degrees at 511 keV by this improvement. Further improvement of the angular resolution (position resolution) will be presented until 2015 spring. Also, we are developing the next ETCC by increasing the thickness of the scintillator from 1 rad. to 2 rad. and the gas pressure from 1 atm to 3 atm which improvethe detection efficiency by a factor of $$>$$ 5 at 511 keV. By these improvements, the imaging time of mouse is expected to be reduced from several hours with to $$<$$20 minutes for lots of kinds of RIs with the energy band from 0.1-2 MeV.
