**7. Summary and future outlook**

The application of CAP plasma technology in the biomedical field has opened up new frontiers in science and technology. It has reached new heights of scientific progress in recent years and has been successfully applied in numerous applications, ranging from sterilization to wound healing to killing cancers. Three CAP devices have already been certified for clinical use for the treatment of chronic and infected wounds. Even if many details regarding the mechanism of interaction of plasma with biological matter are still not clear, some basic principles are known. The biological and medically beneficial plasma effects are primarily triggered by the plasma generated reactive oxygen species (ROS) and reactive nitrogen species (RNS). While CAP plasma has already reached standard medical care status in some areas, such as sterilization, disinfection, wound treatment etc., only primary and pre-clinical data for its effects are available in some other areas. A better understanding of the mechanism of its action will allow further improvement and extensions of the CAP plasma technology to achieve its full therapeutic potential. Also, the development of new plasma devices and modifications of the existing ones will open up new opportunities. In this case, international standardization of the methods to characterize the plasma devices is required to allow better comparability of results obtained from different findings.

It cannot be hypothetically omitted that CAP plasma application does not have some minimal adverse consequences at the molecular level. All these findings and the odds are subject to ongoing investigations, but the current results indicate that the various benefits of CAP plasma outweigh the unproven negative effects. What we all foresee is that the CAP plasma is on its way to clinical routine. Essentially a multidisciplinary research platform is growing with experts from many different fields like plasma physics, biochemistry, molecular biology, medicine etc. to address the issues with synergetic approach.

In the 20th century, laser technology caused a medical revolution with swift development. It successfully got integrated into medicine and created its own medical field called laser medicine. Now, CAP plasma has the chance to repeat this history and to be at the forefront of scientific and technological progress in medicine of the 21st century.
