Curcuma Longa Extract as a Sensitizer for Singlet Oxygen Generation

In this work, the spectral study of aqueous extract of Curcuma Longa (Turmeric) to determine the photodynamic properties. It is established that due to the absorption extract light of wavelength 400-450 nm and intensive fluorescence in the red region of the spectrum, this extract can be used as a sensitizer of singlet oxygen (1

Polarized plasmon resonance spectra of electrochemically modified titanium surfaces with gold nanoparticles

In this paper, the plasmon resonance on electrochemically modified titanium surfaces synthesized by anodic dissolution method has been studied in the presence with gold ablative nanoparticles. The permittivity functions and reflection coefficients of p- and s-polarized light spectra on the titanium oxide surface of various modification (roughness) have been analyzed. Spectral features of the negative refractive index in the area of surface plasmon generation on the rough titanium-oxide film interface have been also presented in this paper
