The idea to use chemically activated vesicles for the degradation of toxins in waste areas is rather obvious. But as long as the whole area must be covered with such mini-reactors, many questions, not the least economical ones, remain open. The situation changes as soon as these reactors become mobile. Then, working with ecologically and economically reasonable amounts of agents may be sufficient to achieve the necessary level of "cleaning". We believe that there are several possible fields of applications e.g. environmental remediation or medicine, but we know not enough to make reliable statements about the effective applicability of mobile multi-vesicular systems. We emphasize that such applications require considerable R&D; efforts, but, of course, offer also considerable economical benefit.
