Microscopic measurement of circular dichroism spectra.

چکیده
A microscope device to measure the circular dichroism (CD) spectra of a specified microscopic region of chiral samples was constructed by combining of a couple of objective lenses and a CCD camera, which was installed in a sample chamber of a commercially available CD spectropolarimeter. By using this apparatus, high quality micro-CD spectra in the 60 x 60 microm region of samples could be measured. Micro-CD spectra of thin film of chiral DNA samples on glass and a natural kidney bean leaf were measured, and the potential of the micro-CD apparatus was successfully demonstrated.

In the near future, design of a new generation of drugs targeting proteins will be required. Considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. So far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. In these studies, use of spectroscopic method...

The centrifugal liquid membrane (CLM) cell has been utilized for chiroptical studies of liquid-liquid interfaces with a conventional circular dichroism (CD) spectropolarimeter. These studies required the characterization of optical properties of the rotating cylindrical CLM glass cell, which was used under the high speed rotation. In the present study, we have measured the circular and linear d...

We have developed and improved the beamline for vacuum ultraviolet circular dichroism (VUV-CD) and linear dichroism (VUV-LD) measurement in the storage ring TERAS BL-5 at AIST, Tsukuba, Japan. This beamline equipped with the four-period Onuki-type crossed undulator [1] as an insertion device. Since natural VUV-CD is known to be weak signal, at most 1 % of photo-absorption, high-sensitive AC mod...
