A method of generating pulses of nitric oxide comprising:
atomizing a liquid source comprising water, NO2-, viscosity agent, and, non-detergent surfactant generating liquid droplets;
pulsing the liquid droplets onto a substrate constructed from a porous hydrophilic polymer having pores with an average pore size, a substrate thickness, and a particulate reductant disposed within the pores and on a surface of the substrate forming a film, wherein the particulate reductant has an average particle size, and the film has a surface density of the particulate reductant and a film thickness; and
generating the pulses of nitric oxide,
wherein the particulate reductant comprises one or more compounds selected from the following structures:
(croconic acid),
(dihydroxyfumaric acid),
(p-toluenesulfonic acid), and,
(2,3,5,6-tetrafluoromandelic acid).
