Pulsed microwave induced light, sound, and electrical discharge enhanced by a biopolymer

Pulsed microwave induced bioeffects

“…We previously reported the generation of light, sound, and electrical discharges in DALM solutions by exposure to pulsed microwave radiation [7]. A variety of mixtures were used, but the process was not optimized.…”

“…As previously described for other DALM solutions, the nitro-DALM peroxidizing solution was exposed to 10 pulses/s (6-s pulse duration at 1/2 pulse height) of 1.25-GHz radiation with a peak incident power of 2-MW forward power [7]. The sound and light produced were recorded with a RCA BK-6B M-11 017A microphone and low-light cameras (ITT model #F4577 black-and-white camera and an Optronics DEI-470 integrating color camera), respectively.…”

“…The final dilution of the DALM was 1 : 100 0. A detailed description of the reaction mixture has been previously published [6], [7]. The filter, with the BA spores, was inserted into the tube to the level just below the meniscus of the fluid.…”

“…The nitrate reductase gene is responsible for the biosynthesis of DALM [6]. This polymer demonstrates thermochemiluminescence, continuous and pulsed, when peroxidizing solutions containing bicarbonate, or other sources of carbon dioxide, are exposed to microwave radiation, continuous or pulsed, respectively [7]. Here we examine damage to anthrax spores with high-power pulsed mi- Fig.…”
