A gold-deposited optical fiber sensor system based on surface plasmon resonance (SPR) was developed for optical measurement of neuronal activity. To enhance the sensitivity of localized SPR and to make a precise and safe contact with the cellular membrane, we designed a tapered optical probe of 1μm diameter at the tip of the fiber. By wet etching and gold evaporating processes, pencil-shaped optical...
Surface plasmon resonance (SPR) is a well-known optical technique for detection of protein absorption or dielectric concentration on a metal surface. In this study, we developed an angle-scanning SPR biosensor that accurately measures the amount of mineralization using MC3T3-el cells without any damage to the cells. Since there have been few accurate methods to quantitatively measure mineralization...
A wavelength interrogation-based surface plasmon resonance (SPR) biosensor has been investigated for a detection of avian influenza DNA (AI-DNA). The hybridization reaction between AI-DNA and the immobilized oligonucleotide probe on a gold surface was monitored. The results showed that SPR biosensor can provide a linear detection suitable for quantification of AI-DNA hybridization as well as a large...
A new type of 2-dimensional curved position- sensitive neutron detector is developed for ammplication at single crystal diffractometer, which covers 70deg in horizontal and 45deg in vertical direction. The prototype development of this curved detector is aimed at testing of technical feasibility of detector parameters such as internal structure, new method to build-up anode and cathode planes' build-up,...
