System and method of producing and providing an antimicrobial agent that exerts an extended residual effect

A method of sterilizing or disinfecting a target using the sterilization and decontamination system that comprises a structure, at least one nozzle positioned on the structure, said at least one nozzle being fluidly connected to an antimicrobial solution source, and at least one radiation emitting device positioned on the structure, said method, comprising:

• dispensing antimicrobial solution from the at least one nozzle positioned on the structure of the sterilization, disinfection and decontamination system to apply the antimicrobial solution to a target;
• and
• emitting radiation having a wavelength of about 150 nm to about 600 nm from the at least one radiation emitting device of the structure of the sterilization, disinfection and decontamination system,
• wherein the radiation is emitted on the antimicrobial solution before, after or while the antimicrobial solution is applied to a target to produce a residual synergistic effect with the antimicrobial solution, the antimicrobial solution and the radiation working synergistically together to produce a greater antimicrobial effect and for a longer time span than when the radiation and the antimicrobial solution are applied separately.
