- •
A method for safety evaluation of NTP plasma treatment of biocontaminated liquids is provided.
- •
Escherichia coli and 位DNA in isotonic or acidic liquid are mixed and exposed to plasma.
- •
Single molecule measurements demonstrate the effect of NTP bacteria decontamination on extracellular dsDNA.
- •
There is correlation between the bacteria inactivation and the extracellular dsDNA damage.
- •
The NTP safety versus the decontamination effect is evaluated.
