A novel power supply for medical implants has been developed. A wireless near-infrared power transmission recharges a lithium secondary battery in the power supply. A photovoltaic cell array embedded under skin receives near-infrared light through the skin and charges the battery directly powering an implanted device. We have shown that, for a photodiode(More)
A B S T R A C T We present a method to develop single-wall carbon nanotube (SWCNT)/polymer composites into arbitrary three-dimensional micro/nano structures. Our approach, based on two-photon polymerization lithography, allows one to fabricate three-dimensional SWCNT/polymer composites with a minimum spatial resolution of a few hundreds nm. A near-infrared(More)
The present study was undertaken to clarify how spinal muscarinic receptors are involved in the antinociceptive effects in thermal stimulation. Intrathecal (i.t.) injection of the muscarinic agonist McN-A-343 inhibited the tail-flick response to noxious thermal stimulation in a dose-dependent manner (31.5 - 63.0 nmol). This McN-A-343-induced antinociceptive(More)
Because of their exceptional local-field enhancement and ultrasmall mode volume, plasmonic components can integrate photonics and electronics at nanoscale, and active control of plasmons is the key. However, all-optical modulation of plasmonic response with nanometer mode volume and unity modulation depth is still lacking. Here we show that scattering from(More)
Osteoblastic mineralization occurs during the early stages of bone formation. During this mineralization, hydroxyapatite (HA), a major component of bone, is synthesized, generating hard tissue. Many of the mechanisms driving biomineralization remain unclear because the traditional biochemical assays used to investigate them are destructive techniques(More)

In the last couple of decades, the spatial resolution in optical microscopy has increased to unprecedented levels by exploiting the fluorescence properties of the probe. At about the same time, Raman imaging techniques have emerged as a way to image inherent chemical information in a sample without using fluorescent probes. However, in many applications,(More)
In the title coordination polymer, [Mn(C6Cl2O4)(C2H5OH)2] n , the Mn(II) atom and the chloranilate [systematic name: 2,5-di-chloro-3,6-dioxo-cyclo-hexa-1,4-diene-1,4-bis-(olate)] ion lie on crystallographic inversion centers. The geometry around the Mn(II) atom is a distorted octa-hedron involving four O atoms of two chloranilate ions and two O atoms from(More)
Direct laser writing through two-photon polymerization lithography is used to fabricate 3D nanostructures containing aligned single-wall carbon nanotubes (SWCNTs). SWCNTs are aligned in the laser scanning directions while they are embedded in the structure. The alignment is induced by spatial confinement, volume shrinkage, and the optical gradient force.(More)
In the title compound, (C12H25NH3)2[Cu(C6Cl2O4)2(C2H5OH)2], the Cu(II) atom lies on a crystallographic inversion center and is coordinated in a distorted octa-hedral geometry by four O atoms of two chloranilate ligands and two O atoms of two ethanol mol-ecules which are trans to each other in the axial positions. In the crystal, the Cu(II) mononuclear(More)
The title complex, [Co(C21H16N4)2][Co(NCS)4]·CH3OH, consists of one [Co{C(py)4}2](2+) complex cation [C(py)4 = tetra-kis-(pyridin-2-yl)methane], one [Co(NCS)4](2-) complex anion and a methanol solvent mol-ecule. In the cation, the Co(II) atom is coordinated by six N atoms of two C(py)4 ligands in a distorted octa-hedral geometry. In the anion, the Co(II)(More)
