Nanophotonics and DNA: New approaches
Vasil G. Bregadze, Zaza G. Melikishvili, Tamar G. Giorgadze
The aim of the present work is spectroscopic and thermodynamic study of DNA catalytic properties in the following processes: a) redox; b) formation of inter-strand cross-links; c)…
Forster Resonance Energy Transfer and Laser Fluorescent Analysis of Defects in DNA Double Helix
Vasil G. Bregadze, Zaza G. Melikishvili, Tamar G. Giorgadze +4
Real time laser induced fluorescence spectroscopy usage for microanalysis of DNA double helix defects is shown. The method is based on Forster resonance energy transfer (FRET) in i…
Point Defects in Double Helix Induced by Interaction of Silver Nanoparticles with DNA
Vasil G. Bregadze, Zaza G. Melikishvili, Tamar G. Giorgadze +3
Interaction of DNA-silver nanoparticles (AgNPs) complexes with H3O+, Cu2+ and Cl- has been studied by spectro-photometric, spectro-fluorimetric and differential scanning micro calo…
Conformational Transitions in Silver Nanoparticals: DNA and Photoirradiation
Vasil G. Bregadze, Zaza G. Melikishvili, Tamar G. Giorgadze
Photoirradiation of silver nanoparticles in water solution of NaNO3 (0.01M) and in dissolved DNA was investigated by spectrophotometric and thermodynamic kinetic approaches. It is…
Nickel (II) Ions Interaction with Polynucleotides and DNA of Different GC Composition
Vasil G. Bregadze, Irina G. Khutsishvili, Sophie Z. Melikishvili +1
The goal of the work was to study the role of GC alternative dimmers in the binding of DNA with Ni (II) ions. The method of ultraviolet difference spectroscopy has been applied to…
Atom-Photon Interactions with Respect to Quantum Computation: Three-Level Atom in Two-Mode Field
G. Giorgadze, Z. Melikishvili
In the paper, analysis of a quantum optical system--three-level atom in a quantum electromagnetic field is given. Evolution operators are constructed in closed form.
Real time noninvasive cancer diagnostics
Z. V. Jaliashvili, T. D. Medoidze, Z. G. Melikishvili +2
Laser illumination of tissue results in a characteristic fluorescence emission spectrum whose features depend on the type of tissue, viz., healthy, adenoma or malignant. Hence meas…
