Remote controlled in situ reaction method

A reaction system comprising:

• a reaction device including:
• a body structure adapted for positioning in an environment;
• a remotely activatable control element coupled to the body structure and including a magnetically or electrically active material, wherein upon absorption of an electromagnetic field control signal the remotely activatable control element responds by changing in at least one dimension;
• and
• a reaction region mechanically coupled to the remotely activatable control element, the reaction region at least intermittently in fluid communication with the environment, the reaction region including a first material capable of modifying one or more of the rate or kinetics of a chemical reaction at the reaction region, the reaction region changing in dimension in response to a change in dimension of the remotely activatable control element, wherein the influence of the first material on one or more of the rate or kinetics of the chemical reaction is modified by a change in dimension of the reaction region;
• and
• a remote control signal source capable of generating an electromagnetic control signal sufficient to be absorbed by, and produce activation of, the remotely activatable control element to change the remotely activatable control element in at least one dimension to thereby modify the influence of the first material on one or more of the rate or kinetics of the chemical reaction.
