Ultraviolet C intensity dependence of decontamination efficiency for pathogens as function of repacked metamaterials with screw channels

Eur Biophys J. 2024 Apr;53(3):133-145. doi: 10.1007/s00249-024-01702-2. Epub 2024 Feb 28.

Abstract

A new method for repackaging optical metamaterials formed from quartz spheres (fibers) of various diameters is proposed for ultraviolet C disinfection of infected liquids by pathogens (viruses and bacteria). The main idea of the new equipment is connected with the rotation of a contaminated fluid by screw channels within a metamaterial matrix prepared from UVC fibers/spherical optics, to improve the decontamination efficiency. In demonstration of the viability of this approach, dynamic and static inactivation of Baker's yeast via Ultraviolet C radiation regimes are used in this paper to show the efficacy of decontamination within the screw channels.
