WebMay 4, 2016 · Cardiovascular diseases (CVDs) have been the prime cause of mortality worldwide for decades. However, the underlying mechanism of their pathogenesis is not fully clear yet. It has been already established that reactive oxygen species (ROS) play a vital role in the progression of CVDs. ROS are chemically unstable reactive free radicals … WebMuch higher production of reactive species (H 2 O 2 and NO 2–) was revealed in the polymer solution than in water after plasma treatment. The amount of RONS generated in gelatin is greatly improved with respect to water, with concentrations of H 2 O 2 and NO 2– between 2 and 12 times higher for the longest plasma treatments.
WebNov 30, 2024 · Plasma-treated water solutions (PTWS) allow the delivery of reactive oxygen and nitrogen species (RONS) to cells and tissues for different purposes. The mechanism of RONS formation has been clearly modelled in simple liquids like water, by assuming a plasma-driven process independent from the liquid. WebThe byproducts of oxygen plasma ashing are not toxic. It’s more environmentally friendly than the wet etching process. Energetic electrons inside the plasma can break down oxygen molecules and generate reactive oxygen atoms. Oxygen radicals can then oxidize the photoresist and generate high vapor pressure by-products CO, CO2, and H2O.
