The optical spectra of the photonic crystal structure is shown to be controlled by changing the structural parameters of
plasmonic nanocomposite layer. Variation in particle size and volume fraction has an effect on the number and
magnitude of defect modes in the optical spectra. The defect-mode splitting is found to be determined by dispersive
properties of nanocomposite layer and PC mirrors.
The study highlights the effect of different modes of in vivo laser irradiation of mice using a PFL8LA laser with λ = 1560 nm, pulse duration of 1,4•10-12 s, peak power of 3,72•103 W and average output power of 20•10-3 W on the lipid peroxidation parameters: conjugated dienes, ketodienes and conjugated trienes, malondialdehyde, Schiff bases and the activity of antioxidant enzymes - catalase, glutathione -S-transferase and superoxide dismutase in erythrocytes and plasma of mice. Two groups of mice received a total dose of 3.8 J/cm2 per group, but the 1st group was irradiated only once, while the 2nd – four times. Significant differences in the parameters of the 1st and 2nd groups indicate different effects of the irradiation modes on redox-dependent processes in red blood cells of mice.
In the present work the effects of high-power femtosecond laser irradiation on a functional condition of red blood cells
and neutrophils in vitro have been investigated. The data on parameters of the lipid peroxidation - antioxidants system,
hemoglobin level and rigidity of red blood cell membranes testify destabilization of the membranes under the influence
of the given laser. The study of phagocytic activity, anaerobic and aerobic metabolism of neutrophils, and rigidity of
their membranes allows to suppose the dose-dependent effect to be stimulating.
