A method and a system for producing a change in a medium disposed in anartificial container. The method placesin a vicinity of the medium at least one of a plasmonics agent and an energymodulation agent. The method applies an initiationenergy through the artificial container to the medium. The initiation energyinteracts with the plasmonics agent or the energy modulationagent to directly or indirectly produce the change in the medium. The systemincludes an initiation energy source configuredto apply an initiation energy to the medium to activate the plasmonics agentor the energy modulation agent.
