A system includes an ultraviolet light source, such as light-emitting diodes, disposed between a first ionic grid and a second ionic grid. The first and the second ionic grids have opposite ionic charges and a plurality of silver nanoparticles disposed thereon. The ultraviolet light source is configured to emit, onto the first and the second ionic grids, ultraviolet radiation having a wavelength of between about 100 nm and about 280 nm. A biochemical detector may be located adjacent to the first ionic grid on a side of the first ionic grid opposite the ultraviolet light source. The ultraviolet light source, first ionic grid, and second ionic grid may be located within a housing connected to a gas mask, and a membrane filter may be disposed between the gas mask and housing. The housing may include a power source connected to the ultraviolet light source.
