Our lab developed the method and a reactor to generate plasma-activated nanobubble water (PANBW). Several applications of PANBW are in the pipeline, including wastewater treatment, biofilm inactivation, green fertilizer production etc. The PANBW was produced by injecting plasma species into nanobubble water (NBW). The size and concentration of the nanobubbles present in PANBW were comparable to NBW, but with enhanced antibiofilm properties. The state-of-the-art nanoparticle tracking analysis showed that PANBW were stable for a long time with not much change in the size, concentration, and stability of nanobubbles. Our current research showed that the PANBW treatment could effectively inactivate the tested mixed-species biofilms, resulting in several log reductions in the bacterial biofilm population. Currently, we are working to improve microbial inactivation and wastewater treatment treatment efficacies of PANBW.
