[ 1 ] - FT- SERS Study of Adriamycin - DNA Intraction

FT-SERS (Fourier Transform Surface Enhanced Raman Scattering) of adriamycin and its complex with DNA is reported. It is shown that in agreement with previous Raman studies the interaction of adriamycin with DNA takes place through an intercalation mechanism. The presence of a new band at 731 cm-1 suggests that ring D of adriamycin is not involved in the intercalation process.

[ 2 ] - Infra-red and Raman Spectroscopic Studies of Infected and Affected Dentine

Diagnosis of infected and affected dentine is an important factor in clininal restorative treatment of dentine. In this study, the IR and Raman spectra of the sound dentine, infected dentine and affected dentine are reported. The structure of infected dentine and affected dentine has been compared with the sound dentine and hydroxyapatite. It is shown while the infected dentine has lost its...

[ 3 ] - Raman Spectroscopic Studies of Bioactive Materials

Bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. In this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. The structure and bioactivity of these samples based on their interaction with simulated body fluid (SBF) have been determined. In-vitor, using the Raman s...

[ 4 ] - FT-Raman Spectroscopic Studies of Nd/YAG Laser Irradiated Human Dental Enamel

FTR-Raman Spectra of human dental enamel, both laser-irradiated and untreated, are reported. Spectra are compared with hydroxyapatite. It is evident that unlike the CO2 laser, the Nd/YAG laser does not induce any chemical change in dental enamel.

[ 5 ] - Structural Analysis of Hirudin Using FT-IR and FT-Raman Spectroscopic Techniques

FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.

[ 6 ] - FT-Raman Spectra of Saffron (Crocus Stivus L.); A Possible Method for Standardization of Saffron

FT-Raman Spectra of Saffron (crocus sativus L.) with a partial assignment is reported. Based on the Raman data, it is concluded that main pigments in saffron are crocins and crocetin. It is proposed that the quickly attainable FT-Raman spectrum of solid saffron, may be used as a means of saffron standardization.

[ 7 ] - Effect of Cyclosporin-A on the Order and Dynamics of DPPC model Membrane Systems

Laser Raman spectroscopy has been employed to investigate the effects of cyclosporine-A on the order and dynamics of DPPC (Dipalmytoyl Phosphatidyl Choline) midel membrane system. It is shown that the addition of small amount of cyclosporine-A to a DPPC dispersion disturb the system and changes the order/disorder parameter of the model membrane.
