JOURNAL FREE ACCESSIn this paper, we demonstrated two label-free detecting methods of biopolymers. We found that the membrane array which immobilized small molecules was effective for the detection of the protein using THz-TDS imaging system. And a label-free protein sensor, which is based on the resonant transmission phenomenon of a metallic mesh, was proposed in the terahertz wave region. By using this sensor, we demonstrated the highly sensitive detection of small amount of protein and the label-free detecting of biotin-streptavidin or biotin-avidin interactions on a PVDF membrane.View full abstractDownload PDF (16049K) -

JOURNAL FREE ACCESSCoherent anti-Stokes Raman scattering (CARS) microscopy and microspectroscopy have become powerful techniques for three-dimensional vibrational imaging of chemical and biological systems. Recently, a significant progress has been made of multiplex CARS microspectroscopy, in which a spectral coverage broader than 3500 cm-1 has been achieved using a white-light laser source. In the present study, we have used a photonic crystal fiber (PCF) to generate a white-light laser and used it as the Stokes light source in the CARS process. Owing to an ultrabroadband spectral profile of the white-light laser, a wide range of the vibrational resonances can be investigated.In the present study, we have performed label-free, multi-color imaging of biological samples using multiplex CARS microspectroscopy.View full abstractDownload PDF (7972K) -

JOURNAL FREE ACCESSResonant x-ray scattering (RXS) is a very powerful technique to detect the charge distribution and magnetization density with a synchrotron radiation source. Recently this technique has been applied to study charge-, spin-, and orbital-orderings in strongly correlated electron systems. In this paper the cross section and the scattering amplitude of RXS are given on the basis of the interaction between electrons in matter and electromagnetic wave.The atomic scattering factor becomes a tensor instead of a scalar through the resonant process. Charge and orbital orderings of perovskite manganites have been studied using the RXS technique. It is shown that the RXS intensities have characteristics in energy, polarization, and azimuthal angle dependences. Finally an outlook for the RXS technique is briefly mentioned.View full abstractDownload PDF (11417K)
