Description

Highlights: • The improvement of non-linear model of interaction of radiation with pathogens was proposed. • The increasing of the contact surface between the contaminated liquid and photonic-crystal fibers (or photonic crystal) is demonstrated. • Experimental schemes for improving of relative decontamination coefficient are proposed using the properties of photonic-crystal fibers and photonic crystal. - Abstract: We propose a method of decontamination using photon-crystals consisting of microspheres and fiber optics structures with various geometries. The efficient decontamination using the surface of the evanescent zone of meta-materials opens a new perspective in the decontamination procedures. We propose different topological structures of meta-materials to increase the contact surface of UV radiation with contaminated liquid. Recent observation of the trapping of dielectric particles along the fibers help us propose a new perspective on the new possibilities to trap the viruses, bacteria and other microorganisms from liquids, in this special zone, where the effective UV coherent Raman decontamination becomes possible. The nonlinear theory of the excitation of vibration modes of bio-molecule of viruses and bacteria is revised, taking into consideration the bimodal coherent states in coherent Raman excitation of biomolecules.
