Liquid NO and RSNO platforms
A plasma-treated N-acetylcysteine (NAC) solution that holds nitric oxide and releases it on demand. Available to research partners as a research-use reagent.
Where it stands
During treatment the solution turns from colourless to bright pink within about 10 minutes, and its sulfur odour disappears. The colour stays until NO starts to be released, then fades. A pink colour that fades as NO leaves is typical of S-nitrosothiols. We are now confirming this with UV-Vis scans of fresh samples taken during treatment.
NO release is measured in the headspace with a calibrated electrochemical detector. Chemical identity: UV-Vis and nitrite/nitrate tests, published in Plasma Medicine.
Next step. Measure the S-nitrosothiol (RSNO) content directly with the Saville assay, then in vitro work on release kinetics and antimicrobial and antibiofilm activity against P. aeruginosa and S. aureus.
