Novel plasma-based technologies that offer maximum efficiency at minimal environmental costs are expected to further promote the sustainable societal and economic development. Unique transfer of chemical reactivity energy from gaseous plasmas water takes place in absence any other chemicals, but results a product with notable transient broad-spectrum biological activity, referred as plasma-activated (PAW). These features make PAW green prospective solution for wide range biotechnology applications, purification biomedicine. Here, we present succinct review how novel, efficient methods based on non-equilibrium reactive plasma chemistries can be applied low-cost natural sources produce applications while same time minimising process steps dramatically reducing use expensive and/or hazardous reagents.
