Summary of the Project
The main purpose of this Project was decontamination of polluted/ infected surfaces and/or liquid (water) by interaction with metamaterials, thin films produced by pulsed laser technologies and cold (non-equilibrium) plasma.
Combinatorial pulsed laser deposition (C-PLD) and combinatorial matrix-assisted pulsed laser evaporation (C-MAPLE) are simple technologies for transferring and depositing thin, uniform and adherent inorganic and organic nanoparticle films with high versatility and deposition rates. The fabrication of combined multi-oxides, biological sensitive molecules (multi-antibody microarray) with variable composition in miniaturized structures will be achieved by the 2 technologies. The synthesized structures will be used for the detection of NO2, SO2, CO, chlorine, pesticides, or biological warfare agents.
The new detection and disinfection mechanisms using the surface specific of metamaterials in the presence of UV laser pulse was established
The model descriptions of the nano-sensors for the toxic molecules and viruses (comparing their optical absorption) was proposed.
The models of the photo-transformation of the toxic molecules and the action of the light and cold plasma on the viruses and bacteria near the surfaces were established as the function of the spectral diapason, dose and other parameters of the ultraviolet radiation.
The quantitative models of the influences of coherence and duration proprieties of the laser pulse regimes emitted by the coherent sources on the contamination zone were established during the realization of the project.
The new possibilities for the decontamination of infected water were realized using the cold (non-equilibrium) plasma generated by microwaves. The new mechanisms of decontamination can stay on the base of modern equipment for defence against CBRN agents.
Sensing properties were expected to be related to nanoscale system dimensions and depend on variable composition of metamaterials.
